monies paid into a non existing account

I have been to the store on the 25th of november 2015 to find out the amounts to settle 2 of my cell phone contracts. I spoke to one of the female consultants which gave me the amounts of 4300 and 2600 respectively to make once off payments inwhich i will get my benefits till my contract lapses. I have deposited the amounts to their bank acc which she has supp**** me and also entered the reference and she has given me. I called the call centre a few days later to find out if the monies reflected but only to find out that no monies where paid in. On the 8th of december 2015 i visited the store again and spoke to Sudhir. Who got a case number for me stating the ref number giving to me by the previous consultant was incorrect. I gave sudhir the two deposit slips and my id to have it sent to the call centre. Today the 15th of december 2015 i spoke to Noniko from the call centre. She said that the deposit slip for the amount of 4300 is only sent through. In all of this the branch at midlands mall showed me pathetic service. Till today my account has not be sorted. The store has not yet contacted me for their negligence. Neither did the initial consultant call to appologise.
