Experia SA dont take Debts off your credit profile when you paid it in full!

One thing about your ITC report is that Experia SA doesn't update your credit score.I am not on debt review or anything but still my report says that I'm an poor player.Im not behind on any of my accounts the accounts that I paid in full still shows that I'm behind on my accounts.So I can't apply for car finance to buy a better car for myself.I only have three account now,ack,truworths and Rage and still the old credits is still on my profile that a paid more than a year ago! I went over my credit limit on one account,when I bought clothes,I paid for in for the amount I was over and still you list it on my itc,that I went over my credit limit.I paid for it,and the i still have the same amount credit available.I paid for the rest.Come on,I phone I couple of times not to get an answer from you.How do you think people must get credit and be credit worthy if you don't take debts off that people paid in full.
