Very bad service with undisclosed Ts and Cs

This company is ******** people. My internet is been suspended from May but I received invoices for every month that I must pay for the the months that I did not have the internet, when I call and asked them they said it's a month to month I have to pay because they paying for my services and it's their Ts and Cs, When I registered with them I explained to the lady that I don't want a fixed contract I want a month to month service so that I pay as I use it due to this pandemic because we no longer working frequently and we agreed the term and conditions that were read to me never explained that I will be paying every month even if my line is suspended. Ive been calling them trying to get to the bottom of this but theyve been telling me about their Ts and Cs and I asked for the copy of my recoding cos when I was talking to the lady who singed me up the first thing she said to me was please be aware that our calls are recorded and will be available apon request. Now that im requesting for it I cannot get it, it's been months now still haven't received it but invoices I receive every month, I now have to pay R3369 for the internet I did not use, more especially in this state we in with no jobs or working remotely at home, or working short days and yet this company is repping us off. It is really not fair. They don't disclose their Ts and Cs then the next thing you find your self having to pay for what you don't know. They are *****ing us day light. I'm still waiting for till to date. The next thing I'll find myself with a very bad credit score because of them.
