worst internet provider

Have you tried it without the VPN you are using?

I have no problems in Captchas in NOS, and never seen problems reported by NOS users.

Do you have a Chrome Extension to automatically accept captchas?

I can tell you for sure, its not a ISP problem.

I know, this is ISP problem. I tried my friend internet connection and all was fine.(vodafone)

Like I said, I find it hard to believe that you're the only one with that issue.
Dont take me the wrong way, I'm not defending NOS, but it's a issue that if it was ISP sided it would be more widespred.

Lets try to take this in other manners:
What type of Internet do you use? Mobile Internet?
Is the vodafone network with a Mobile PEN?

I use this internet:

And my friend internet is vodafone 400/100 Mbps.

Are you tried with the same pc?

Of course

Yes, I called the support earlier but you did not solve this issue. The problem is that you collect data from the customers. But this is illegal. Google detect this suspicious activity therefore I can not use that website where the customers must use google recaptcha.
It is very easy. When I use another internet conection with the same laptop then it working well. But when I use my internet conection (NOS) then I can not login or register because google block the access.
I do not want call you again because you promissed that you will solve this issue but so far nothing happend.
And I know you do not want solve this big problem.
If you really want solve this issue then I will give you my Customer ID and you can change the modem or you can whitelist my IP address or you can stop collecting data from the customers. I do not know exactly what you will do it.

I think you will never answer as you will never solve this big problem.
