Cell C Call Centre does not care about their customers

I have been putting Cell C on Hello Peter numerous times & still nothing gets sorted out. Yesterday i got a call from a guy by the name of Abdul regarding my account being in arears. I tried to explain to him that my account was not debited & he told me that i have used the money knowing that i must pay which is not the case. I told him i will make arrangements to pay whatever amount it is off & get i get a sms from the bank that Cell C debited me R845 i am not happy about this as he refused to also listen to me no matter how upset i was. I am not the only customer complaining about Cell C. Is this the way Cell C does business?
