Get calls all the time from 479-289-8921, ususally calls 3 times in a row, couple times a day. The last call I got, I told them I was with the FBI that this is being recorded and could I help you, a young voice answered and said "are you investigating this number, I said yes, he or she hung up. Havent got a call since. This young voice sounded like a child around the age of 8 to 10 yrs of age. Hopefully, this will stop these calls.
