Yeah I keep having problems with this number as well calling my cell. I ignored it for awhile but since they kept on calling me I got pissed and so the wife took the phone called them back and they kept putting her on hold, finally someone asked her for my social and she just hanged up. Similar problem happen with an 887 or was it 877 phone number that is popular if you google with similar results of what appears to be a scam. I've had enough of these people that if they call again I'll make sure they know I'll take all measures needed in bringing legal action against them.
However don't give these people any information about yourself, if you really were to owe them something you would know and they wouldn't ask you for your personal information.
