Dissapointment - poor service

I am extremely disappointed with Cell C. My husband accidently pushed recurring data bundle in July. I tried to cancel it in September, they told me that they will cancel with immediate affect but I will still have to pay for it. I was told to phone on the 30 of the month to cancel. As I was in hospital, explaining that in a email, I was unable to phone on the 30 September. I phoned on the 01 October to cancel the data bundle. I also requested that they ensure that I don't get charged at month end for something I did not use. Ref ***. I was told that she cant do anything about it. Umpati left a message for Heidi (supervisor) to call me. Up until today no call received. I phoned again Ref *** asking to speak to a supervisor. I was told a mail was sent again to a supervisor, still no call back. The lady Nomkhosi Ref *** was nice, and called me back to tell me that she is working on my request. I once again told her that I will not have the funds available to pay for something that I not going to use. Yesterday I received my statement and whala…...they charged me for the bundle that was cancelled on the 01 October. This morning I phoned again, insisting on speaking to accounts, or supervisor. And I was told that they have a very cleaver system that will automatically credit my account in November, and that they are unable to do any manual changes, As it is all driven by a system with no human support. Very cleaver. I really had enough of cell c. They don't listen to their customers, and in these difficult times that we are currently in, I would have thought they would go out of their way to assist they long standing customers, that have never missed a payment. Please stop the debit order with immediate effect.
