not willing to assist to cancel data contract

This is far form over, When I was called it was to tell me that I need to send the cancellation on a company letterhead. I did not complain about my telephone - which you have to fill out my telephone number on the contact details. It was for the data contract which I had to phone in a couple of times to get resolved- But Vodacom don't have customer complaint department, but get phoned back by people who does not know what the problem is or really care because if Vodacom did they would phone back to resolve the problem not give feedback that is not valid or relevant and try to figure out what the problem is. I have been to 3 stores to get a new contract, last one waited an hour while the consultant tried to get it through, just to be told that the IT department need to clean up the account, they will need to call me back. But Vodacom will try and let you pay for data on higher prices on a month to month after the 24 months expired and than if you want to get a new contract feed you all the bul****.
