CELL C Does it AGAIN!!!

about a week ago I posted a complaint and a rude little twit called me, I told him that it is *** that I get billed incorrectly by Cell C! He also didn't do his homework so he drops the call because I say ***! Come on people *** is not a swear word. Also you want to charge me R280 and I barley use my device! No communication from you saying my contact is ending. A few ladies called me and when I asked them to pleaser call back regarding a new contract none of them did! I was also promised my refund in up to 72 hours! LOL what a joke, I am still waiting! YOU PEOPLE better reconcile my account and get back to me ASAP! This is not the first billing issue I have with you guys!! As for that twit, he better call to apologize for dropping the line for the word ***!!!!
