False information given

I had a contract with virgin active, my account got into areas. I received a call from one of their employees(an Indian guy) regarding my account asking when will I be able to make the payment in responds I told him I don't know because I am unemployed and still a student. I then asked if I can cancel the contract and he said yes I can but I'll have to pay a cancellation fee. I told him I don't want to freeze the account I want to cancel and he still said I can cancel of which I had to pay in total R2212 and I agreed, at the end of the month the debit order went through (on November 2014). This month (01 April 2015) I got a debit order again from virgin active of an amount of R147. I went to them to query it and they say my contract was never cancelled it is still active. When I asked about the amount I paid for cancellation they said the contract was freezed and not cancelled, I asked again if I wanted to cancel it what must I do. They said I must pay another cancellation fee of R1060. Why must I pay a cancellation fee twice whilst the problem was on their side? Why do they hire staff who don't know the terms and conditions? This is total **** and I won't pay for their mistakes.
