CellC Store Mall@Reds nightmare

I had upgraded my cellc contract on the 09th June at 14h30 to a contract that does not really benefit me, and only realized that it was a useless contract when I got home at 18h00 going back to the store within 24hrs of purchasing the contract, the store was on load-shedding. As I had a bereavement in the family, I had to go lay my dad to rest. Returning to the store on Monday after the funeral, I was attended to by a personnel by the name of Rayno who is Afrikaans speaking, and clearly had a battle with the English language, and very inexperienced as everytime he would refer to someone who was said to be the store manager, who was very busy, and was going to call me later during the day after he speaks to his manager. The call never came to say the list. I want back to the store yesterday and was told by the manager that they will not cancel the contract as I have exceeded the 7 day period of cancelling the contract as they could not provide me with the correct contract I wanted. Trying to reasoning with him was a very futile exercise as he tells me that I needed to pay R5099.29 x 2 for each contract if I cancel. I am dismayed by CELLC as I have been a loyal customer to them.
