Caller ID showed up with above number. When I answered, a recording said "I'm sorry, that is not a valid extension. Please try again." Then it hung up.....
Received a robo call regarding credit card debt - I carry no credit card debt - so I waited and dialed the extension to speak to a person. I asked to be taken off their calling list. The woman from the scam company was RUDE and said "tough sh*#", then "byebye" and hung up. Put them on the reject list.
