no confirmation of contract being cancelled

i cancelled my contract last year, did not receive a confirmation letter, someone online reactivated that account using my details, i picked this up when i started getting billed again. i went to my branch in Galeria , they could not help me, they said i must go to Gateway branch, i went there and they told me the ***** department will assist me. I have now been handed over to the lawyers for not paying something that i did not take. it is carrying on from last year, i still have no feedback accept there is some investigation. I need my name to be cleared and resolved ..tired of the bad service and communication with Vodacom.
