OUTSTANDING REFUND

I sold my house and I cancelled my ADSL line, acc no ***, in February 2015 at Telkom The Glen - reference number AI***. Telkom never cancelled the debit order on my account and continued to bill me. I sent emails to the accounts department via their website regarding this. I called 10210 a number of times but it is impossible to hold on for 60/70 minutes a time to speak to a call centre agent. In May 2015 I went to Telkom the Glen to resolve the matter and was told that my February 2015 cancellation was NEVER even processed! I resubmitted everything and received an sms on 15 June 2015 from 27 *** informing me that the ADSL line was now cancelled and that a refund of R1373.50 was due to me. The sms never promised when the refund would be made and another month later (July) and I still have not received this refund. The Telkom accounts department are not responding to my emails requesting the refund and Telkom The Glen says they cannot assist with refunds. I understand that there is some restructuring happening at Telkom but that is an internal matter and should not affect a customer or customer service. I would like my refund!
