My contract was loaded incorrectly ,a smartplan 100 with Samsung S6 32GB for R399/month, by the Telkom telesales person and was being charged R495 per month. I opened a case on 25 January 2016, ***. I have spend 4 hours on the phone, stood in the queue at the telkom shop for 2,5 hours and 21 emails later to [Email Removed] which is the customer care email address. No body has contacted me or provided any feedback. The standard response is \The back office is still busy with your case, they will contact you for feedback.' Its been months!!<br> <br> To make the situation even worse on my February invoice is a cost entry for Deal Charges of R8960!!! <br> <br> Could somebody please contact me and provide feedback?"
