Who called from 3212344766

When we answer no one speaks. We are a business and after two or three "hello's?" they hang up. When you call the number back it only gives a recording and says if you want to be taken off their call lists to please press 1. I called with my number hidden so as not to offer them whatever they are scamming for.

Same thing happened to me

Stupid - important message for your blah blah blah sales / solicitation

Same message. Did not answer as I assumed it was a telemarketer.

I answered and the recording said my Google account was 50% complete.  No other information no other comments.  No clue
