Who called from 2155250073

Did you guys post anything on Craigslist?  I did.  They called and never left a message, just the same as with all of you.

Unknown call on my cell phone, so I didn't answer. Been getting a lot of those lately.

I did post something on CL a day ago. Your comment makes me think it's related. Never left a message here either.

I didn't answer, didn't recognize the number. When I got to my work desk phone I called it back, busy signal; indicates it is a robocaller type spammer. This # is now blocked on my phone.

This number just called me, but I didn't post anything on Craigslist. I didn't answer and they didn't leave a message. I get a lot of "unknown callers" but this was a first for this particular number.
