received a call from this number today. who are they? notice a lot of hits when this number is googled

I just received a call from this number.  A young woman asked for me by name.  I said who is calling and she hung up.  Then I tried to call the number back but I got an automatic recorded operator intervention which said that this was not a working number.  Obviously this is one of those numbers that are set up to verify cell phone numbers.  It is impossible to track them.

Got a call and they hung up when I answered. Called back but they said it was not a working number.

When I use truecaller to search it comes up your magazine co....

Ive gotten several calls from this number. It comes up 'your magazine' and when you answer they claim to be asking how you like the 'your magazine' subscription theyve been mailing. However, I dont ever get any mag's in the mail and ive never even heard of it. Every time I tell them this and that I want them to stop calling they hang up. I mean EVERY TIME!!! I cant get them to stop calling. Ive even tried to call back and it doesnt work. Im on the no call list, but I guess it doesnt work.
