Contract Cancellation

On the 6th Sept I wished to cancel my wifi contract,which is still within its cooling off period.The contract never didn't start as yet and my cooling off period(still time to cancel contract) and 12th Sept.After one of the managers or supervisor heard that I want to cancel the contract he tried to price me in giving my me more data usage or anything I should mention,that evens made me more determine to cut ties with Telkom.After cancel the contract via online as it was told to me with one of the consultants I recieved a SMS stating that they recieved my cancel and that they are preparing the paperwork and one of there consultants will get back to me no later then end of business that day or I will receive a email advising that contract has been cancel.Today I phoned again still within my cooling off period and lucky it was one of the consultants that help me on Friday and she told it's best to go into store and tell them that I tried to cancel my contact.Telkom you guys really sucks quick to sell contracts and get delivery done but such a pain to cancel one's contract.
