Round 2 with Vodacom- Issue unresolved

My previous issue with Vodacom has not been resolved. Today I was contacted by a very helpful lady named Maureen from Collections. She advised me that a dispute was not logged. She explained to me that I was correct in how my billing is done, and that the TEAM LEADER from CUSTOMER SERVICES was incorrect as to how the billing is done. The TEAM LEADER assured me, on WEDNESDAY 3RD NOVEMBER, that she will investigate and revert to me on SATURDAY 6TH NOVEMBER. TO DATE I HAVE NOT RECEIVED FEEDBACK. Not even a dispute was logged during this time. Highly unacceptable service from Vodacom. Please, I need this to be resolved ASAP. Please kindly contact me urgently. Also, please do not say I have been contacted when I have not.
