Vodacom ignores ********** upgrades

Had 4 data lines which was supposed to expire after two years. When it didnt i went in to Middelburg Mall branch to cancel them. Only after 3 or 4 visits was I advised that all 4 lines have been upgraded at the Witbank branch., but they dont know who can help me (guy tried to contact several people but one is more pathetic than the other). They keep deducting money from my account and now owes me over R10 000. the docs were sent to the customer service centre, and they then tell you that ***** is dealing with it, but still - the debit order goes off and the lines are still active - even though they have my affidavit, id and the ********** documents not even completed properly in Witbank, as well as the id that was **********ly used (which does not even look like me). These docs were submitted at the beginning of October already. No one can give you name or number of someone you can actually speak to - you just need to email and the branch guys just pull their shoulders up. Worst service ever and no one knows what is going on in their organization. Have the staff members name that did the upgrades - were obviously too lazy to check that the signatures and id matched.
