bad credit even when it was paid

<p>Worst thing iv ever done was sign up with this company when they first opened, like 6 years ago i know i paid up my account when i closed it. And i come to find out that my credit score was affected by this saying i owed them like R3000.00 thats no joke. cause when i pulled my credit score from transunion they were my one default when i try contact this company or person the number does'nt even exist.</p> <p> </p> <p>completely not acceptable </p>
