Very Bad Company Holding old info against me

I had a edgars account a few years ago , i was retrenched and my account fell into arreas and the account was handed over to attorneys for collection<br> <br> I have paid the account in full and was issued a letter confirming it <br> <br> Its now more than 2 to 3 years paid up and when i tried to apply for a new account it does not allow me because it still picks up the old information<br> <br> I spoke to so many people from accounts and even the store who advertised that the information was supposed to be deleted of their system as the account was fully paid up<br> <br> They don't appreciate their customers !!!
