appalling service

This query back dates to November 2014. I was assured that the case was resolved, which is not true because I was promised that the cancellation fee would be waived, only to find they debited my account for R5775 in March. I called the call center to rectify the matter, they logged a case. I now face a default on my bank account due to an incorrect debit from telkom side. It's two weeks later and I still haven't had any response for Telkom regarding this case. I called back today and spoke to a Tanya, her attitude was horrible and now once again I am stuck . I am now receiving countless texts saying that I'm going to be listed at the credit bureau. Not once has telkom even sent me courtesy airtime or data for all the trouble they put me through since November 2014. I would not recommend Telkom service to anyone.
