Received call from this number about 1 hour ago. Who / what ever this is did not leave any message. Suspect it's the same bill collector that is calling every time from a different spoofed/bogus number.

Caller I.D. only read "Dover, DE". Since I don't know anyone in Dover, DE, I picked up and hung up.

No real name. Just Dover DE. Did not answer and they didn't leave message
