Cell C dishounarable

The only reason for the 1 star is when u add on prepaid bundles u get extra for bonuses and coz I can't seem to delete it, otherwise I feel they don't deserve even half a star. I cancelled a data contract last year. Got the full and final settlement amount. Paid it. Checked 2 days later that the service is suspended and no amounts owing. This was 7 Nov 2018. No funny debits on 1 Dec 2018. 1 Jan 2019 they over debit my account. Now, I have another contract for my phone. There has been 11 + calls back and forth about this. Everytime the person on the other end has absolutely no knowledge or record of any previous calls in this regard. I reversed said debit order back into my account and paid the active contract amount manually. That actually reflects on their system. But they cut my service today. They say they will suspend the active paid contract because I refuse to pay the incorrectly billed amount of the cancelled contract. I mentioned that the reason why I cancelled the data contract in Nov was coz I am unemployed. I told them today that by them unfairly suspending my service, I can't continue to look for work. No mercy. No proper communication. No emails, nothing. Just these call centre people who have no clue about any previous conversations with regards to the exact same topic. I think it is pathetic that such a big company have robots as employees as they cannot think or see or hear past their own little rhyme of total bull twang over and over with every phone call . Not once has somebody in an authoritative position tried to communicate with me. They don't talk with you.... They talk AT you. So sad. I will take my meager little bit of business elsewhere and I will surely influence everyone I can not to do business with Cell C. So the prepaid airtime, data and smses I bought extra on the contract is also blocked, which means they are *****ing that. I have to close my bank account now as I have been informed that their system will not stop debiting my account
