Personal information

For the past couple of months I have been getting accounts of another person, I have reported this numerous times, since December, I have been told that it was sorted every time,. In February 2015, they contacted the person and I was told my info was taken off. 14 March 2015 I get an itemised billing error statement of this person. I reported it again on 17 March 2015, I got a call where I was told the cannot remove my e-mail address from the account because I am not the account holder, they have to contact Vodacom, I phoned again and I asked to cancel my contract and remove my info, I was told it was removed and I asked for confirmation that my info is removed from that account and I received a blank fax cover letter email subject saying email removed, nice Vodacom.
