I too received a call today, 2 Feb 09, from this number. I answered but no response from their end. A nuisance call - my wife is sleeping after being on night duty. Fortunately I was here to stop the phone ringing.

Answered a call from this number just now. I spoke to an Asian Lady who said she was calling for a debt company and her researchers had told her I was in debt, which I'm certainly not. She had my surname, address and number, but the first name she had was "Mercy", which is nothing like my real name. When I asked her where her researchers had got her information from, she couldn't tell me. The lady seemed to have a poor grasp of the English language, so I couldn't get anything out of her at all!
