Telkom disappoints once again!

I went to the Telkom store in clear water mall requesting for an upgrade and I was assisted by Zodwa Dlamini. I was interested in a Huawei P7, I filled out my forms and left them with her she gave me her email address so I can forward the remaining documents that she needed to process this upgrade. On the 18th March I emailed her the o/s documents on [Email Removed] she emailed me back within 10min to say they do not have the P7. Within 20min I emailed her back saying let me decide, she responded to say I should let her know as soon as I make a decision. A few hours later I email her back asking if there are any other Huawei devices, she didn't respond. The following day 18/03 I email her again and i cc'd [Email Removed] Asking why she isn't responding to me and also informing both parties that I would like to cancel my contract and attached all the documents required for a cancellation, including my landline, current cell number and email. Nobody has ever attended to my request, Telkom are still debiting my account even though I asked so nicely that I want it cancelled. So when applying for an upgrade I got 100% friendly assistance but it's a problem to cancel???<br>
