11 Years ago my business went belly up and I had a personnel bank loan of R50 000.00. Not having an income, I was ordered by the court to pay R50.00 pm.

This debt was sold to a debt collecting company some years ago and they are now getting aggro with me to start repaying more. They say that I now owe R150 000.00.

Can someone tell me:
1. Can the principal debt of R50k increase to R150k?
2. Can they get a new judgment against me as I had one for this already?

Thank you
