The call was for a renewal for a free tech trade magazine.
Some additional info
These are call centers who are provided with a particular list from their client.
If you ask them to place you on the DNC list they can only do that for that particular list.
If they get another client and you are on that list they will call you again.
There was a day I got called 4 times from the same number with renewals for 4 different magazines.
Most of these are for trade publications and they have to verify if you still qualify for the free subscription.
Received call. I answered but no one responded. I called back and it went to voice mail saying the "Google Account" was available and to leave a message.
I get a call from this number twice a day, everyday. They never leave a voicemail. I've attempted to call back a few times and get "this google subscriber is not taking calls, please leave a message" (or something to that tune).
It occurs to me that I recently signed up for a Best Buy customer card and gave my telephone number to them. I wonder if that's what's triggered the spam calls.
