JET *****elant transactions on my account of 9****!?????

I opened a Jet account in July, not even 9 days later after my account has been opened, "someone phoned the call centre to say I lost my card and need a replacement!" The additional card was issued in my name (in Cape Town - but I live in Jhb)!!, linked to my account, they made two purchases, one at CNA Lakeside mall for R4500.00 and one at Edgars in Rosebank, brand new phone @ R3999.00!! Firstly, Jet cannot explain how they issued a card on my name with no identification!! Secondly how do they purchase things for such huge amounts and not ask for any identification in stores!!!!! Now, almost a month later, I still cant use my account!! Nothing is sorted out!! And every time I phone, they say next week!! This is unacceptable JET!!! You don't bother to phone me to tell me about the progress on this ********** transactions or nothing!! No feedback or updates what so ever!! I want this sorted out, and I want feedback on who did this on my name!!! The only people that had access to ALL my details was your STAFF that works where I went to pick up my card and activated my account!!!!
