Do not ever call these numbers back as "nobody" above recommends...Scam!!  Calling the number back only validates your number, and then it will never, ever come off the telemarketers lists!  "Nobody" probably works for the telemarketers!!!

By the way, I just got a call from this number, left no message, blocked...

I did not answer the phone I looked up the number and found it is probably a scam
