Who called from 2066298615

This number just called. Caller ID said it was from Grants - that's all. I didn't answer and they did not leave a message.

Call from this number, when I answered they hung up.

Same thing, they hang up as soon as I answer.

I got a call from this number, no answer, i tried calling it back and they don't answers. caller id reads VersaDebt.  Called it back several times repeatedly, it never rings... just eventually goes to a busy signal

I live in New Mexico.  As a new resident, my new phone number receives several unwanted calls a day.  I have registered as a "do not call" list and was annoyed to receive a call from Versa Debt.  There was no answer when I picked up the phone.  I called the number back and it doesn't even ring!  I googled their name on the web and can't find anything on this company.  I wonder what's their game?
