Received call however did not leave a message. I called he number back, without displaying my caller ID, and the call simply disconnects. Most like a scam call.

Caller: Don’t know. Didn’t answer

Constantly calling from similar numbers once you block a new number is calling at all hours of day & night.

Numbers need to be harder to obtain by scammers

I got a call from the same number. I didn't answer and they didn't leave a message. I also received called from the same set of numbers with different ending numbers like 40, 41, 42 and now with this 44.
