Getting billed for data bundles never purchased!!

I'M SUPER FRUSTRATED WITH VODACOM!<br> <br> BEING ALL LOYAL CLIENT FOR 15 + YEARS AND REALLY STARTING TO GIVE UP!<br> <br> I USE DATA TOP UPS VIA THE SELF HELP SERVICE *111# AND *123#. IT'S THE THIRD TIME NOW THAT I GOT 'AN ERROR HAS OCCURED' MESSAGE. SO YESTERDAY I PHONED THE CALL CENTRE TO LOAD 1GIG OF DATA. THEY ALSO ASSURED ME THAT NOTHING HAS BEEN LOAD PRIOR TO THE PHONECALL(S) THIS MORNING AGAIN RECEIVED TWO SMS'ES OF 2GIG'S OF DATA BEING LOADED ON MY ACCOUNT. AGAIN ON THE PHONE WITH VODACOM AND AGAIN SERVICE CALLS HAS BEEN LOGGED TO REVERSED THE EXTRA GIG OF DATA. NO ONE GETS BACK TO ME! 1ST CALL HAS BEEN LOGGED ON THE 18TH! AGAIN BILLED FOR UNNECESSARY DATA. THIS IS THE THIRD TIME!! GETTING SUPER FRUSTRATED WITH VODACOM!!! YOUR \SYSTEM\" IS NOT WORKING! YOUR SERVICE CENTRE NEITHER! SURELY I CAN NOT BE THE ONLY ONE??? "
