Trying to cancel a R179 contract.

I don't really know how to put all this detail down of how messed up the process is to cancel something. Calls that go on for 30 mins and you are transferred to another agent with no approval when they just done and not willing to help. Verifying details 5 times and repeating what you need just to be transferred to the next person who can't help. Being told you can only go in to an MTN store to pay the outstanding amount by one and then the other in retentions say there is and EFT option, but they don't have banking details, so they transfer you to customer support for that. 1st time I am told to pay R670± to cancel early, a month later it has gone up to R690.76, on the same call, I pay the R690.76 and ask to go back to retentions so that I can cancel as it is now paid, they tell me its now R760±! I am asking for my phone call recordings as this needs to be heard. The way I have explained my experience doesn't do it justice. I will continue to hunt to get these calls. Still trying to cancel it.
