you try to call back and they're busy.The number displays but unknown...

I don't recall the name of the call centre calling, CH-something-or-other.  They wanted to confirm that I had received my free sample of meat.  I said no and that I didn't want to either.  They hung up rather quickly.  Had I said yes, they would have attemped to arrange the drop off of free meat (a half-pound of ground beef) by two very-high pressure sales people who would want me to sign a contract for 6 months of their meat deliveries before they would leave.

I answered and they did say they were from Ch-something and were asking if I wanted my free sample of steak. I said, no thank you and she was polite and hung up.

this had called here  sporadically last year, started up again.  No messages so telemarketer or scam.

got phone call from this number about 5 mins ago. did not answer.

Me too, no idea who
