Very bad service from Jet (Edcon) ***** Department

In 2016 i was made aware that I have a Jet account that is in arrears as I was trying to get an increase on my credit card limit and my bank informed that I do not qualify for an increase due to that I have been listed on credit bureau. I was very shocked as I have never opened a Jet account in my life. I contacted Jet ***** Department about this ********** account that had been opened in my name and I had to follow all the instructions in order for this cleared, which I did. Now, in 2020 as I'm busy trying to apply for a home loan I'm told that my application cant be processed before I get a letter from Jet that states that this account has been settled. I have been phoning Jet ***** department for the past three weeks everyday trying to get this settlement letter but I have had no feedback at all. Every time I phone I'm told that I will receive the letter by the end of the day. It is very frustrating that I have not received any help from your ***** department and this is affecting my opportunity of getting a home loan. All I need is to get a SETTLEMENT LETTER FOR AN ACCOUNT THAT I HAVE NEVER OPENED IN THE FIRST PLACE.
