Still Receiving Bills

I have recently moved, failing to get hold of telkom at their fantastic and efficient call center (sarcasm) in order to cancel my ADSL and old line, I had to go directly to a Telkom Direct. <br> From there I was notified that I still had 2 months left on my contract and could not cancel without paying penalty fees. I advised the Teller that I was more than happy with paying the cancellation fees - she then cave me a *** and I was on my way. 2015/04/14<br> <br> A month Later I received yet another bill for my data usage, ADSL and telkom line which by now has no longer been in use. Thereafter after waiting 2 hours on hold I eventually got hold of someone who I hoped could solve this issue. After quite some difficulty the call Rep gave me a dispute *** and advised that they would contact me within 7 working days to resolve.<br> 10 working days later a very efficient lady (Christa) called me and advised that I had now been credited and everything has been sorted.<br> It's now June and I have received yet another bill ?!?<br> Telkom what is going on? I have never had any issues with debt or payments....how do I resolve this
