CASE OF ***** NOT BEING RESOLVED BY VODACOM

An additional number has been added to my Vodacom contract WITHOUT my knowledge or consent, for which I've been paying for a YEAR now. I've tried contacting Vodacom's ***** dept on numerous occasions - no replies. I've tried the ***** line - no answer! Call centre agents are of no help either! So Vodacom owes me thousands of rands and I can't even cancel my debit order or my lines that I actually SIGNED for, will be cut!!!!
