Pathetic Service Provided

On the 23rd March I purchased R55 + R29 airtime consecutively using my cellphone banking for my modem so I could purchase 1Gig using my modem. When I connected to my modem in order to purchase the data the balance only reflected the R55 recharge and not the R29 so I refreshed and watched my balance drop to R48 as I paid out of data bundles waiting for the R29 recharge to reflect, this never happened. I further purchased another R29 and R5 which did reflect and I purchased the 1Gig so I could check if the initial R29 had deducted from my account which it had. To date I have spoken to three call center consultants with no help, the first lady I spoke to on the 23rd told me to go to my bank, I'm not sure why. I then called on the 24th and spoke to Akhona she also didn't provide a solution and promised to call back before the close of business that day but never did. The last consultant (Ephrahim) simply ended the call abruptly without providing me with a solution or allowing me to speak to his superior or logging a query with the technical dept for me. I am disgusted at the level of service provided. Why did the R29 never reflect, what happened? No answers.
