***** dispute no feedback

On the 15th of November I noticed multiple debits on my account from vodacom. On contacting the call center I was told it was for 5 new contracts I had taken out on the 13th. Of course I had no knowledge of these contracts. I was advised to contact their ***** disputes team with certain documents which I duly did the next day. When I had no response after a few days I sent a follow up email. Still no response. Then today vodacom debits my account with a huge sum of money - in the tens of thousands. This is money I do not even have in my account so I am now in a huge overdraft and my legitimate debit orders are being returned. Upon contacting the call center I was told it was for premature cancelation of the 5 contracts WHICH I HAD REPORTED AS ********** TO THEIR ***** TEAM!! I am now in a position where I have to change all my banking details and take time off work to sort this **** out. Not only has the ***** team been useless and failed to provide any feedback but now vodacom has ****** more money from me, leaving me with a mess which I now have to try and sort out. I have already ported my voice number from vodacom to another network. I anxiously await the expiry of the data contract so that I never have to have dealings with this company again.
