I used to get calls from this number it is a scam, I git grants, IRS, lawsuits and non-profit calls from them and others that tell me to call that number to claim my "prize" this number is a scammers number.
this is the number of a scammer I have had calls from them through out the year and last year for grants, non-profit, IRS, and threats of lawsuits by the military. every time they call they say they are in Washington D.C. they are persistent and called me every other minuet when I blocked their number they use a spoofer to change the number but my phone has no part of it the number still shows unavailable Des Moines Washington.
