Who called from 5039466813

No message left and can't call back

Said name was Oliver from the Duct Cleaning service and he wanted to schedule to clean my ducts.  I would consider this a scam

I have had this same number come up in the past, the phone rings about four times and then they hang up. Our answering machine picks up on the fifth ring

Keep receiving calls from this number.  When I answer, they hang up.

Calls when I answer they hang up
