JET STORES REQUEST FOR SETTLEMENT LETTER IGNORED

I had a Jet Stores account about 3years ago. I was unable to pay my account due to loosing my job and it was in arrears. I am now willing and able to pay for my account in full. I would like to settle the account and receive a settlement letter. When I visited a Jet store in Queenstown, I was informed that my account was not found on their system. The bill still exists and it shows negatively on my credit score. We contacted the Jet Head Office I was not assisted at all. I made contact with RCS, Nimble group and ITC, there is still no solution to my problem. I have sent numerous emails to Jet stores begging them to please send me a settlement letter so that I can make payment but I have not been assisted with anything. I am able and willing to pay, I just need the settlement letter. I even contacted Experian several times requesting their assistance, and still nothing.

Please give me a direct number that I can call, a name of a person that can assist me with this, their email address that I can use in order to get assistance.
