I have received a few calls from this number. By mistake I answered today and on the other end there was just a guy "singing" AAAAAAaaaaAAAAAaaaaaaaaaAAAAA and then hanged up.
I keep a call from this number - someone seems to have sold my information after i tried to get a payday loan on-line. Now i'm getting a bunch of these - notice other people are getting them too - they dial wait for you to answer and then say one or two words and hang up - real nuisance
