Debited R13508 for phone not received

Following our conversation, went to the branch on the 17th of Sep to collect my phone which was not available because of a system error.I asked the branch to cancel my application on a number of occasions. On 19 Sep I app**** for a contract via MTN direct.I ordered a Rose gold 64G Iphone 6s.Was assisted by Thandeka, who promised to contact me. That was not true. I called to check the status of application, and no one could help. I spoke to Hope, Sipho etc. But Thandeka only called me at about 14:30 on the 25th of Sep. Apparently my previous application was not cancelled, hence the delay. My phone was sent out for delivery to Thabazimbi on the 30th of Sep, I was not notified or called about the delivery in advance. The driver called me at 14:00 I in Pretoria. As if that was not enough, on the 31st of September, MTN debited R13 508.03, yes no joke.I wonder what this is for
