Who called from 3126380648

First off, this is not a legit business. If they were, they would have to obey the Do Not Call laws. This is most likely a hacker or scammer calling with a fake caller ID. Most of these scum bags call from outside the U.S. India, Pakistan are the biggest offenders.

this number keeps calling with only a deep when the call is answered.

Did not answer

this number has called multiple times at the ungodly hours of 2 - 3:00 am
