41 days and still not resolved

As discussed prior to my departure, it was agreed that on my arrival the incorrect handset was to be collected on the 01/04/2016, and the contract was to be terminated, and NOTHING has happened. I really need to get this resolved and what makes matters worse is that Telkom has a much better deal on the iPhone 6s , so I am left with no other option , firstly your customer service is useless and secondly people are being ripped of with ridiculous pricing, \ cell c the cheapest network \" is is absolute nonsense, please have your courier collect the device and cancel this contract, I am sure lots of customers will be moving away from this network, due to pricing and availability, If anybody reads this , compare deals with other networks, there is big competition out there . I think it's now time I get the ombudsman involved, we have a paper trail and recorded conversations should his matter not be resolved. "
