Who called from 5621559959

This caller asked for my husband. Then we were disconnected. He seemed surprised to get an answer. I question why they are phishing!? Anyone else have this number call you?

Just called here twice in a row. No messages left. Weird to get a call with a 155 prefix.

received a call this afternoon.  CID:  NAME NOT FOUND

didn't answer and no message left.

I see that I commented on this number last month. Just called again, same weird number. When I answered there is no reply only silence then a hangup. CID says simply "name unavailable".

missed call/no message. This is not a valid # (the 4th digit can not start with a 0 or 1) so it must be spoofed.
