Same thing happened to me.
Very odd.

I got a call from this number on my tracfone - only people who have my tracfone # are my husband and my son !! of course - I did not answer it -  I have no caller ID, just shows number

ditto here. got this number, did not return call.

Got called! Luckily I didn't answer...stupid thing!

i just got a call on my business cell #.  i am not amused.
