Cancelled on the 4th Jan - still not cancelled

So this is the second time on Hello Peter, first time on the 4/2, Telkom responded to say they would respond within 24 hours I think. I have called about 8 times and emailed as many times regarding the cancellation and conversation of my contract to pay as you go. received a credit on the statement dated 26th Feb only to be charged on the same statement for March, one asks - surely not! so I will carry on trying to cancel, I am on the phone at the moment to Telkom. What amazes me is that its says hold on we are experiencing high calls, maybe if clients did not have to phone 8 times they would have less calls. This cell phone is still active and it does not seem to have been converted to pay as you go, so I guess you guys are carrying that cost too because I certainly am not.
