Hello

I could not find any line to reach NOS  via email or any texting line

I call the number sometimes operators don't speak english

I'm writing here that at the store the sales person was clear about my monthly payment will be 17.5 eur 

I opened the invoice and it was 

€58.26

This is not correct

I would like to learn why 

IF anyone knows a way to reach them by texting ?

I’m very unhappy with their service yet I already buy the number and don’t want to change.

Thank you.
