Problem with Billing

I took at telkom contract for a galaxy s8 back in May 2017. I did an online application, i was then contacted by the Telkom sales representative for online applications we then went through the application over the phone . She then told me that my application has been “Pre-approved “ . For final approval my account had to be debited the full amount of the contract package which is R629, which will count as my first debit order. I received the device mid June n i was billed in July for the month of June and July and to my suprise the money debited in order for my contract to be aproved is not on my account statement . I’ve been trying to sort this out since Aug 2017 ,now its Jan 2018 and the R629 i paid Telkom mobile is still nowhere to be seen on my account statement. Case number ********** 9.

Im tired of calling Telkom to have this resolved, always have to wait plus 20 minutes for the next available call center agent to answer my call.
