Telkom service

<p>Since I took out out an contract at Telkom a few months ago I experience problem with the deduction of monthly subsription. On month they deduct the amount of R469 and then they let me know the next month I must pay R469, some months they deduct the amount, and today I received a call again that I own Telkom R939 after I aready paid every month. How am I going to solved this problem, I already went to varous Telkom stores as well as phoning them</p>
