Hi
I have had the same problem with Lowell, i.e. they have demanded payment for a debt owed by someone sharing my name, whom they claim to have traced to my address!
When I got the first letter I sent it back with a 'not known at this address' note.
However, I recently received another, threatening me with Red Debt (which is another of Lowell's trading names). So I emailed the Credit Services Association (of which Lowell's is a member) to register a complaint about Lowell's conduct. The email address is claire AT csa-uk.com. I copied the email to Andrew Bartle (Andrew.Bartle AT lowellgroup.co.uk) , and I had an apology from him first thing the next morning! Strange, eh? The CSA sent me a complaint form which I have completed and mailed back to them. Although Lowell say they've removed my name from their records, I don't trust them, and I certainly don't think they should be allowed to get away with hounding innocent people!
