I receive calls every day from 44-207-485-6003.  I know that is a UK number, probably London from what I can tell.  I also know that most likely it's an American Company bouncing off of that number just to confuse things.  They are offering some sort of debt consolidation type deal, but if you ask questions they hang up.  There is a recording in the beginning saying the company name is "Account Services" then the operators will tell you the company name is "Card Services".  These people just need to be arrested.  Obviously they're up to something.
