Bad bad service!!!

I have requested to cancel 2 of my contracts that expired about 4 months ago. I phoned in about 3 times to cancel but is still being billed every month! I have also changed my kids numbers to R39 per month since September last year till today it have not been changed. So since September last year I’m paying a bill for stuff that I don’t want. I am really sick of this **** network!!! They even played a joke on me and promised me a Black Friday deal to stop me from going to Mtn! Guess I was the joke. Thanks ***. I loved being the joke ! Now I just wish my contracts can end and I have no business with this company ever again!!!
