Who called from 7204588155

Same as Selina

I've gotten a call from this no. 2 times. Each time they've asked for the head of the house and I say he's not available and can I give him a msg. They VERY quickly say no msg. we'll call later and hang up before I can say anything else!  Don't know what's going on or who it is!

A male caller asked if my deceased spouse was at home and I told him, "No," and hung up.

Get calls from this number with various Caller IDs on occasion but don't pick up and no message is left by the caller.
Am curious as to what these calls are about though.

Disabled vets.  They've used other numbers too.
