Pathetic service Cell C

I wish there was a zero rating am really upset with the level of service I receive when I am cancelling your contracts BECAUSE THE SAME THING HAPPENED IN DECEMBER!. I called you guys on the 25 March at 12h53 and spoke with Tebogo, I asked for a full amount that I need to pay when am cancelling the contract and she advised that I need to pay R253,29 (cancelation fee) and R504 (Bill for March) I fully paid the settlement amount of R758, I did a follow up on the 26 and sent POP and I have received confirmation from you guys on the same day that the contract has been cancelled. Why the hell did you debit on my account again last night the R504?????? I just called again now at 09h48 Katlego is telling me the debit was for March, how but I paid you? Because this shows me the level of inconsistency that we get from consultants its pathetic! Can I get my money back before I take this further, I can't be doing the same thing with you, you are inconveniencing me!
