Who called from 7203157900

I had a missed call from 720-315-7900. I called back and a recording said to "press any number to be removed from the list". I didn't press any number because I knew it's some type of scam.

They called me around 6:36 PM. I didn't answer, and they didn't leave a message. I'm guessing it was scam.

I also got a call from this stranger who is this mystery caller?!?!?! I would like to know.

Someone called e and I don't know who I've got a call from this number before and I don't know anyone in Colorado who is this mystery caller I would really like to know.

Who is this!!!!!!!?????!!!!!!!!
