BAD SERVICE

I am trying to CANCEL A CONTRACT I have with cell c due to being charged heavily on a mobile contract. I took out the sim card and bought a prepaid which means that I do not use their contract sim. A consultant assisted me and told me to pay R3203.78 (which I paid last Friday 5th june) if I wanted to cancel the contract early, she also stated that it (3203.78)included the current amount for June. I just called the call centre and I'm being told they still have to debit my account at the end of June but upon cancellation they said it INCLUDED this month. I am sick and tired of being exploited by cell c. Im being transferred from one department to the next without out any answers. I want nothing to do with this company ever again. Can someone assist me so I can cut ties. I have emails as proof that I have been in contact with a consultant. I really am fed up.
