Cell C *****s from Customers & Doesn't Care

I have never in my history of dealing with cell companies, experienced such ********** customer service and ineptitude. I clphoned in Oct 2020 to cancel my contracts with Cell C as I was emigrated. The service operator confirmed the cancelations. I then called in November to check on cancelation, and was told only 1 contract had been canceled. I canceled once more and was told all was in order. I called again to follow up before I left in December and was told the contract still had not been canceled and that I had to pay a cancellation fee, which I duly did. It is now nearly March and I am STILL being charged every month for a contract I canceled in November! It is daylight roberry. I am actually at a loss as to what more I can do. I have so many reference numbers from my attempts but noone is prepared to help. My advice - stay away from Cell C!
