Vodacom Not helping

on 25th of September I received a message that my email was changed. On the 26th I called vodacom and I found out someone in Bloemfontein has upgraded me account. I don't know what that person took and now i cant get assistance to get the matter resolved. I was sent the ID of the person who upgraded me, the information is my information but the picture on the ID is not no. I didn't request an upgrade. This is *****. I called the store on ***( Loch Logan in bloemfontein) i spoke to Max van Schalkwyk Van Schalkwyk <***> and he assured me the upgrade wont be processed and a case of ***** will be open. But now the upgrade is in effect. I have been calling Vodacom for help but I am sent from pillow to post. Number i have been calling are ***, *** and i cant get any assistance. May someone look into the matter and get these issue sorted ASAP because its my name which is getting bad credit report. I am tired of calling Vodacom because i am not getting any assistance.
