Forcing to pay for no Service

I currently have a big issue with this company, their system first is so backwards that it does not even recognise when they are doing an investigation into a problem caused on their own side, they have been forcing me to pay for a service that I have not been receiving, when you look for help on their WhatsApp chat support or they do is try and convince you there is nothing wrong, basically arguing with the customer as if I don’t know better, little do they know I actually know what I’m talking about. Their new employees are actually very rude for a number of reasons, like flat out ignoring me, cutting the call on my while talking or promising to call back or log an issue but never really doing so..I have a lot of evidence to prove what I am saying is true, WhatsApp messages and voice notes..they are forcing me to pay for a service that I am not receiving, but I guarantee you if my payment was short they would never accept it, so why should I pay for short service how is that fair to the customer. Now my network has been suspended because I refuse to pay for a service I have not being receiving.
