No assistance in ********** accounts opened

InNov/Dec 2013, I signed for 1 contract at the Vodacom Pavilion store. After querying about the amounts being deducted from my bank account, I found out that 5 lines had been opened on my name days after I had been to the store initially. I DID NOT EVEN GO TO THE STORE ON THOSE DAYS! I queried with the store who told me I had to provide my id copy and affidavit which I did. Vodacom forensics said I was liable for payment. In October 2014, I received a letter from Vodacom saying I owe R40000 and I had 30 days to pay. I am not able to get any documentation to prove I signed for the extra lines, I am always told that they do not keep documents at store level. In the interim, whilst Vodacom is wanting to ****** more money from me, my itc score is greatly affected and I am struggling to get things done. This is extremely concerning because ***** occurred in that store and the customers are having to pay the price. I would like to see my documents, it is MY RIGHT as a customer and the cameras in the store must be checked to prove I didnt sign for the extra lines. Please can someone contact me urgently to resolve this matter. It is extremely serious and I would appreciate any assistance.
