Telkom will not resolve my problems

My list of problems that Telkom is not willing to resolve:<br> 1. Incorrect billing for Add On Internet Bundles for a contract customer.<br> Bills for December 2015, January and February 2016 contained charges Internet Bundles amounting to R1873.20. As a contract customer, these should have been reversed. Telkom has not done so yet.<br> 2. Billed twice for one mobile phone:<br> For one of my phones, Telkom billed me twice for November 2015. First R700 appeared in the December bill for November and then R610 in the January bill for November. Telkom has not yet reversed the R610 charge.<br> <br> Telkom is yet to respond to a query raised at the beginning of January 2016 relating to the above. The earliest query on its systems is dated 10 January 2016 and representatives said they would respond within 10 working days. January has gone by without a response. I've also complained on numerous occasions via Twitter since 01/01/2016. All they say is \An update will follow\". I now have a total bill of R5175.55 which contains R2393.20 that i should not be billed for.<br> <br> One thing for sure, they will suspend your mobile number AS THEY HAVE NOW DONE SO AGAIN, no matter how wrong their bills are."
