Charge on my property

[redperil]

Hi About 10 years ago i defaulted on a Lloyds credit card to the tune of £5000. I was taken to court and ordered to pay a monthly sum back every month, which I have been doing. They also put a charge on my property. A couple of years later when PPI reclaims were rife I claimed and was refunded £1000 approx and then i did the same with the charges and was refunded £1500 approx. To my mid the original debt should be reduced by that amount* too and it should be £2500* not £5000. Am I correct in my thinking ??
