ID *****

I lost my ID book last year mid February and I ended up going to get a new one around March after getting an affidavit saying I lost my ID that's why I need a new one. After a few months that's in June I think, am really not sure, jet started calling me telling me I owe a certain amount of money, just then I told them I ddnt open any account so I don't owe jet anything, the lady I was talking to advised me to go to the nearest Edcon store to lay a complain. I then went to a store near my town and told them what happened and they let me fill some form and told me they will call me in a few days to inform me what is to happen next. I waited for their call for a week then I decided to go back to ask them if the matter is solved. When I got there they told me thiers nothing they can do because the ID that opened the card is the same one I have which ddnt make any sense to me because I did say I had lost my ID book and I had to make a new one so the one I have is a new one. I fail to understand even now what they mean because an ID book is always the same weather you make a new one or an old one. I then told them if they can make further investigation because am not going to pay R6000 which I know nothing about, they gave me the store location that the card was opened at and told me maybe if I go there they will help me. I went to the store and told them what happened but they told me they can't help me I even asked them if they can check thier cctv recordings to see if I even went to thier store that day but they told me they only keep records for 3months. Am really very disappointed with the way jet people are handling this issue, right now I can't do anything it has messed up my credit record and it's affecting me so bad because I can't buy anything on credit.
