Account cancelled in February and still paying

I cancelled my month to month Telkom mobile data contract in February 2015 as I no longer have coverage. I was contacted by Telkom mobile early in March 2015,to confirm this, which I did but was told that it would only take effect at the end of March.<br> <br> Surprise surprise still was billed in April, May and June. I once again contacted Telkom mobile at the end of May and then was told there was no record of my cancellation. I then emailed a copy of the cancellation document I signed in February as requested by them.<br> <br> Three weeks down the line and I have had no communication from Telkom mobile and no resolution.<br> <br> <br> Thanks<br> <br> Joshua Brownbridge<br> <br>
