Who called from 2108810901

Called the number back and heard "The survey you are calling about has now finished".  I then hung up and added them to my blocked numbers list.

Ditto.

This is the 6th different 210 number I've had to block in the last week and a half, and all the comments I read from others suggest some sort of survey robocall spammer.  Someone is hitting the 210 disposable/spoofed numbers hard.

Yes exactly same thing happening to me.

Same here.  Saw this number on my caller ID and did not answer.
