I receive call like that also. I am not sure if it is the same number as yours. Looks vaguely familiar. I tried reverse telephine searchs on the call I get and I never get results.

This is one of the many numbers that belong to a company that call themselves United Federal Bank. They are supossedly a collection agency, but they refuse to validate any debts, or give out any address. DO NOT send them any money! They will harrass you and threaten you, contact the FEDERAL TRADE COMMISSION and you ATTORNEY GENERAL and file a complaint
