Cancellation of Services

I have a 1 x Deal SmartInternet 2.5GB Samsung Galaxy Tab 3 P5200 10.1 @ R307.50pm contract with Telkom which was due for upgrade in September 2015. I decided not to upgrade the contract as I was happy with my device and wanted to stick with my contract plan. End of August I was billed R307.50 as per agreement, end of September R 107.50, which made sense seeing that I was now paying for the contract only as the device payment is now settled. From end of October I was billed R 723.04 the same contract! No additional charges added, nothing! The excuse from Telkom is that I am now being billed outside of contract rates because I haven't upgraded. (Regina ***) Okay, well, then cancel the \Contract". WHAT A LAUGH! To get this thing cancelled is a NIGHTMARE! I sent through the request fro cancellations 03/12/2015. On 30-12-2015 Telkom rep**** \""Please be advised Ref. No.(***1) has been logged as per the request in question. Someone will be in contact with you to discuss and advise the turn-around-time it will take to address and resolve this matter. I am still waiting. December's statement is again R513.50. """
