Contract Cancellation problem

<p>On the 28th of February I cancelled my CellC contract and then I got billed R110 1st March, I left this problem thinking it was a cancellation fee I had to pay then end of February came and I was Billed again April , I went in to CellC they told me my account is still active and I should call a number, I called 084 143 and then the person told me she can't give my money back because I had used the benefit of the contract, which is your problem not mine, as I was told it was cancelled. Now she says I'm gonna be billed again end of this month, this number is off since 31st March</p> <p> ********** 455</p> <p>Please assist me as this is unacceptable</p> <p>You owe me R220</p>
