NOS, the worse Internet provider I never seen.

They are totally crazy. The 14 eme day after my order, and because Internet was not working as expected, I had send them a registered letter to cancel my commitment. They had called-me to ask me, in case my connection will be fixed, if i would reconsider my position. I answered OK, let-us try..
Yesterday, (18 days with poor or no Internet) they had called-me and send SMS to advertise a tech will be in my home today.
And, during the time he was exchanging the Modem, they had cut the connection, according to my registered letter , he was surprised, but he said he cannot do nothing to recover-it near their administration, even for testing.
They are totally disorganized and insane.
I'm happy to be finished with this nightmare.

Actually the "Provedor NOS" is pretty much as useless as the "Complaints Book". With these they won't even bother replying - ever. And I speak from experience. After half a year complaining on these books every single month, I am yet to receive a reply. That was years ago...
As for being the worst internet provider, well in Portugal they certainly are but believe me there is a lot worse "out there".
Complain to the "Provedor de Justiça". If you're right to complain, they'll do all the leg work and someone from NOS will call you with their tail between their legs: to fix the problem and offer something in return for all your trouble (like a discount) or to let you get off the contract, if need be.
The "Provedor de Justiça" is above the Provedor NOS. He is not paid by NOS but by the state (i.e. our money) and he has the authority to act when you're being duped. Whatever he decides, NOS is legally forced to act upon it. NOS has no respect for clients, but the "Provedor de Justiça" is not someone they can ignore- ever.
There's a phone line, but I assume you don't speak Portuguese, so you're better off writing them an email to "provedor@provedor-jus.pt". Make sure you attach any documents you have and give them the details of the phone calls, specifically when they were made. They might be able to access those calls too.
I would say good luck, but in Portugal what you need is Patience- lots and lots of it. And the ability to keep a straight face on when you hear something utterly ridiculous.
DO NOT FORGET: make sure you get a piece of paper from them saying the contract is cancelled if that is what you want. Do not do this over the phone. Get the paper and keep it in a safe place - you might need it (they are famous for sending invoices after the contract is over).

Thanks a lot, Lopes.for your precious advices.that I will follow point by point.This model of business is stupid and have no future. It was quite like this in France, few years ago, but they fought so much, the ones on the prices and the performance and the others on the quality of service, that, now we have both,
For a price that would make you cry, 16€ for mobiles with no commitment, illimited phone calls to 150 countries and mobiles, illimited datas in 4G, free roaming, and, for Internet fiber, 1Gb down, 200Mb up, illimited phone cals to 150 countries + mobiles + TV. And now, with a good service.

You're welcome Esperado. I hope it works out for you. Unlike France, things are not likely to get any better soon. There's a monopoly in place and the Establishment are here to stay. There is no real competition, they have their "little meetings" every now and then and set the prices together; it's the same with fuel. You're likely to have noticed the price is the same pretty much everywhere. No, it's not a coincidence...
Also, in Portugal there is no point in complaining, they'll just treat you worse next time and that goes for everything. When you complain you are left with nothing but frustration because you are right, but still you can't change things.
The "ANACOM", that was mentioned before, is meant to be the Authority in charge of all Communications related things, but the thing is they don't have any real authority...
Welcome to the not so great part of Portugal!

One month after the installation of the fiber equipment, my problem of connection breaks is not solved. Despite 4 uploads of so-calling "firmware", i modem exchange (for the same model) 3 visits of so calling "technicians" in my home, dozen of phone calls and hours waiting with this boring music at phone.

No progress at all. That is what I call "Competancy".
If I was the technical manager of this company, all technicians would be fired. And after them, myself ;-)

ps: Don't even try the "8" for having them calling back: rhey never do. Never.
This company is a real shame..

I'm having a similar issue since the 9th of this month. I have contracted 200mb and for the past 15 days I have never achieved more than 50mb, it's mostly around 10-20mb. I've called them countless times. Technical team says the cell that provides internet to my residence area is overloaded, they have to expand, but have no deadline for it. I just received my bill, no credits given, called them again, they say I have no right for credit, and I can't disconnect the service without paying the breach of contract. But somehow it's not a breach of contract for them to consistently provide a terrible service nowhere near what I've contracted.

Anyway, I just filled a complaint with ANACOM online. Don't know if you guys know this magical thing I found out today WHILE ON CALL with NOS.

Don't know if and when they're gonna reply, but I'm gonna keep calling NOS everyday and keep filling complaints with ANACOM until it's solved.

BTW, I live near downtown Porto, anyone suffering from this around me? Let's talk, maybe a class action suit is in our future if they don't get their sh*t together.

If you can prove you don't have the expected service you pay for, of course, you can break the contract with no penalty. Send them a registered letter in witch you give them, for example, one more week to fix your connexion and if not, you will stop the contract with them, because they dont provide their part of the contract. Of course, keep screen copies of all the download tests you had done to proove your situation, and record the phone calls (as they do).

Just one thing to add:
"Technical team says the cell that provides internet to my residence area is overloaded, they have to expand, but have no deadline for it".
Have a record of such an answer. that prove they are dishonest: Selling a connexion while they are knowing they cannot fulfill the promised service.

At least you have an explanation!! Best advice? Move on to another provider if you can. You will never get your problem solved otherwise...
