Cell c is a piece of **** and I've had it with it

I am so sick and tired of cell c's unprofessionalism. This piece of **** company has been billing me R1300 instead of R800 since 2019 March. I have made countless calls, lodged countless complains, been given countless stupid references, been giving false promises to "fix" this and yet once again cell c has just deducted another R1300 from my account today. Their customer service representatives have very questionable skills when it comes to dealing with certain matters, they have this habit of playing dumb and it always ****es me off because sometimes you feel like you are talking to a kindergartener when talking to them and yet you will be using your airtime... If you could see the conversation history between me and them, you will be ashamed for them/just be sad.

What really do I have to do in order for cell C to start taking my complain serious? I requested a refund of all the money this piece of garbage company has ****** from me and I have not received any so far. In fact it's like I never lodged any query because things are still continuig like the way they were more than a year ago!!!

Does one need to take drastic stepsin order for cell c to pay attention/rectify their mistake? I am so sick and tired I swear, in fact I am going to cancel their stupid fiber and go for mweb because their service has been awesome so far. The cell c's fiber internet is not even that great to begin with (and I am not making this an issue at all coz I have other alternatives I am using) but on top of that I am being ****med! NO, there is only so much one can take!

The ticket number is this one: Ticket # [CF094270] , have had it since last year
