1st Debit order not reflecting, cant be found.

Good afternoon,<br> <br> I hate to be a bother, but I have a slight problem.<br> <br> I app**** for the Telkom Smartbroadband Unlimited LTE package at R599 pm for 24 moths in December 2015 , with which I am thoroughly happy with.<br> <br> When I app**** for the deal, the consultant informed me that a debit order will go off my account before I get the package and it will show a credit on my statement, which I was fine with, it went off my account on 12 December 2015, received my package on 18 December 2015, SIM was activated on 21 December 2015 and all was well, until I received my invoice on 02 January 2016.<br> <br> Nowhere on the invoice does it show R599 credit from my debit order, I phoned the billing department, and not a soul can find the R599 credit, so my current balance is R870.81 (R271.81 + R599) which is due to go off on my debit order date.<br> The R271.81 I was informed is the Pro rata amount for December and the R599 my normal amount for January, but where is the R599?<br> I don't want the money in my account, I just want a credit on my invoice of R599.<br> <br> The debit reference is : 121215 NAEDO TRACKED DO SETTLEMEN 0,00 599,00- TELKOM8TA /MAG***.<br> <br> Please assist.<br> Kind regards<br> Morne Roux
