They called my cell.  I called back to see "who" was calling.  Machine answered CRA - I hung up naturally; and looked them up on the web - only to find a rap sheet here.  

I was harrassed 3 years ago about a debt that was 10 years old.  At that time, I called the Better Business Bureau.  Found out it was a scam company that they've been investigating.  They are just nobodies that search your info., find an old unpaid debt, claim that they are going to sue you if you don't pay them immediately.  Unfortunately, a lot of people know that they did have an old debt, feel bad about it, and send this fradulate 'debt collector' a lot of money.  Everytime the bureau is close to catching them they disappear; only to reappear somewhere else, scamming someone else.  The Bureau told me never ever pay an old debt to anyone claiming to be a collector.  Most companies write off debts within 5-7 years.  If in doubt, let it be clearified in court before the judge.
