I looked up 'debt surveillance program' on Google and a debt collection firm, Intrum Justitia have one such program....(posted 8009 days ago)"Debt Surveillance is a unique service from Intrum Justitia that helps you recover debts which would normally be written off as uncollectable.
We put details of the debt on our unique Debt Surveillance system. We then monitor the financial position of the debtor for five years. We do this through a series of letters, telephone calls and visits from our dedicated network of agents.
As soon as the debtor's circumstances have improved, we act swiftly to recover the debt.
The Debt Surveillance programme is available on a no-collect no-fee basis. You only pay commission on actual monies collected, with no hidden costs."
So from the looks of it, you might get letters from suspicious sources, and they will check your credit file on a regular basis to see if you've got any money.
I don't like the use of the word 'subjected' in the letter you received. It sounds like they are going to be looking at your details every day until you give in. Criminals subject their victims to torment and distress.... sounds like they want to do the same thing!!
Read through the rest of this website, especially the Do's and Don'ts and the sample letters and if there is anything you've not done, do it.
