CELL C RIPPING ME OFF ON A 'CLOSED' ACCOUNT

I am so annoyed with CellC and their terrible service. Let me make a long story short. My contract ended in July 2017, I called September, October and November to cancel my contract but they kept on deducting money from my account. December they didn't deduct January they took 2 payments, I called and ask what's happening, I request for a manager he listened to the calls and we came to a conclusion they will cancel my contract on that day and no payments will be taken from my account again(CALLS ARE RECORDED). Two days later I get a call from collections(FAITH) stating I'm in arrears, I told her I don't want to talk to her because they stressing me out, she must talk to Neville Moodley the manager from KZN. I also told her I will send this out to the media, than Faith said, 'Not a problem mam' (VERY SARCASTIC TONE)Today I wake up and more money was taken out of my account. I want my money back into my account and I hope this account is closed because I will take this to ombudsman . This is stressing me out.!!!
