billing error not fixed

TO WHOM IT MAY CONCERN <br> In January 2015 i took out a TOP-UP contract with Vodacom with 2 tablets. In March 2015 i got a bill of nearly R10000.00 i went back to the vodacom store in Canal walk and tried to find out where this amount was coming from. I lady assisted me( cannot remember her name) i gave her my contract she scanned it in and sent it to her manager. i went back again, as i got no feed back from them an this time i spoke to a Denrich King he to scanned in my contract and sent it to the managers. In August 2015 Vodacom debited my bank account with R1500 which is not what i signed for nor is it my contract amount. Vodacom does not give me airtime and i can no longer use my cell phone or my tablets and this is not fair as this is not my error and vodacom is not eve getting back to me regarding this. Thank you in advance<br>
