Cell C accounts a disgrace

In April I took out a contract for wireless LTE. One week later Cell C cancelled all these contracts telling only the stores and not their customers. I spent almost a week trying to connect then my local Cell C store informed me of the problem. They suggested I take out a new contract using smart data which I did. However Cell C still owe me the balance of the contract I paid for in April plus the 20Gigs extra I purchased just before they cancelled the contract that was R799. They passed a credit for May for which they charged me. They still owe me R799 plus the balance of the contract I could not use for April. The local Kokstad store staff are extremely helpful but even they, despite numerous e-mails and phone calls to their accounts dept, all fell on deaf ears. I too have sent 7 emails with proof of overcharge which also fell on deaf ears. They take your money on a regular basis but when it comes to sorting out their wrongs they ignore you and keep your money. Disgraceful service indeed. Imagine cutting new customers off, informing the stores by letter (which I have seen) but ignoring the paying customer. Then keeping their money.
