Who called from 6784516388

Auto-dialer.

Got 2 calls from a wireless number of 678-451-6388. Called me by my first name and said we were owed a refund when we got our mortgage. Problem was the address was for a house we'd never had a mortgage on. SCAM ALERT!!

got call friday a.m 7/22 same as above, refund on mortgage, also knew my my first name

Got a phony call from this number, also.  USA Legal.  If the number is available, surely the authorities can track down who issued the number, and to whom it was issued to.

I did not answer.  Guaranteed scam.
