Who called from 7207081246

I keep receiving a recorded message that speaks in a foreign language and has call me from variations of this number numerous times in the middle of the night and during the day  (720) 708 1299, (720) 708 1366, (720) 708 1288 and many others

Received a call from this number at my place of work.  When I answered, I could hear the phone ringing while I was put in a queue for the next representative.  When I stated the name of the business again, a lady replied, "sorry, love."  Not sure what kind of operation it is.  Seems like a telemarketer or other nuisance caller.

called my office, asked for me by name, waited to be transferred to me, then as soon as I answered and asked who I was speaking with the man hung up
