Cancellation of contract

I have been struggling to cancel my data contract since April 2018 but to no success. I phoned several time to client service and broker lines and spoken to various consultants that have taken my details and still not actioned. They all try to transfer me to cancell/ retentions but the call keeps cutting.

I was given the number 084143 and the call was ringing for close to and hour on hold not sure why they gave me the number in the first place, because it was not usefull.

I am not not sure if there are any activity on the call centre tracking call tracking systems logging to show I did call in and why I did call in.

I was also at the Kuilsriver - Soneike branch at 17h45 only to be told that the cancellations/retentions department closes at 17h00.

Why is it a mission to cancel my one contract if I have a current existing contract.
