Cannot Cancel Line! Cannot get throught to Agent!

We moved offices and needed to cancel our ADSL line at old office. I was told to email [Email Removed] with company docs, letter, my id doc. I did all of this on the 2 Feb 2015 and received a reply saying Telkom Business Retention Centre acknowledges the receipt of your email.(and saying i should send the above docs if i haven't yet).<br> <br> I have not since received ANY reply, and the debit order for March has again gone off my account.<br> <br> At the new premises i still need to connect to telkom, i cannot transfer as its not the same type of line. <br> <br> When i call 10217 to get feedback all i get is: Due to high call volumes there may be a long delay. Its been 20mins and im still holding.<br> <br> How can i cancel this??? Im not even sure i want to connect to telkom at the new premises as the service is horrible(im considering rather just using wireless)<br> <br> WHY CALL IT SMBS Retention Centre??? You are not doing ANYTHING that makes me want to stay a customer.<br> <br> When i called to cancel my office insurance, the Outsurance retention agent convinced to me keep my policy, telkom could have done the same but you are making me so upset i want to go out burn the nearest telkom device.
