TELKOM USED DETAILS THAT I HAD NOT CONSENT TO

I opened a cellphone account with Telkom Direct (Tygervalley) around the week of 18th Dec 2015.<br> I provided : 3 months bank statement, salary advise and ID as required.<br> My Bank statement identified my bank account and my proof of address, to my surprise a month later my statement was delivered to my previous address, I followed on later that I was being billed to an account number I had not provided.<br> Two very important details were missed: 1. Wrong account number<br> 2. Incorrect address, this could have easily subjected me to ***** committed under my name.<br> <br> I went into the store last week 17 or 18 February 2016 and spoke to a consultant (Only black/African female in the store, forgot name) she promised to look up my contract to verify the information and ring me, this is about a week later with no call.<br> My account is now in arrears and I would like to bring it to normal but would like to know where the incorrect details were obtained from as this has now created a poor record in my name and placed my account information at risk.<br> <br> I am failing to understand such blatant negligence.
