Terribly Telkom Service

In June I received my statement from Telkom. On there was an additional nr that did not belong to my contract. I contacted Telkom on the 18th June lodging my complaint to a agent at the helpdesk, she explained that she will log the call, but can't really do anything about it as it must be submitted to the ***** department. I submitted an affidavit and spoken to 4 different consultant and send numerous mails just to hear that my case was submitted to the wrong department by Mogomotsi Mary Zwane on the 11th so therefore she has ignored all my mails submitted to her since the 6th July. I was accused that I can't read and only when I broke it down did they believed me that Telkom took an extra R351.10 of my account for this nr. I have now send another mail to the team lead of the help desk department and they have logged another call for me, and told me to phone back within 3 days because then only will they assigned it to somebody to investigate.
