Service Failure and breach of contract by Vodacom.

I have been trying since the 21st of Dec 2015 to get some type of resolution to my billing issues with Vodacom. On December, 16, 2015 I called into the the Vodacom call centre and requested that my debit order date be changed to an earlier date than that of the 25th. Since then my request was not met and I have taken the iniative to go in to A Checkers to make a payment which My vodacom statement advised as a MOP on the 5th of January 16.I have been since be told that I was advised of the incorrect reference number and my R1738.99 installment has not been allocated and is laying in a dormant easy pay account belonging to Vodacom. I have since spoken to Client Liasson Riaan Underhill who attempted to help me I however My line even after paying my account up to date is still being suspended and is still suspended now. I have tried twice this morning to call Riaan to get feedback and my call has been cut both times. Yolande Nell who is the supervisor at The subscription collections dept has been contacted via email by the Vodacare shop even before I spoke to Riaan and I have never heard from her regarding my account. After over a decade of being a loyal customer I have had it!
