Back brace scam - said I had requested info, which I had not done.

They're baaaaaccccckkkkk!
Scammers!

automated message telling me they're returning a call in which we asked for info on some BS product. Lies, of course, call wouldn't disconnect even after I hung up. Had to unplug phone from my wall in order to get back my own phone line.

No clue who this is. My call block is full, so I can't block them. I just answer, then immediately hang up.
