Who called from 7207355376

They called my cell phone. No message.  No clue who it is.  Only a handful of people have my cell number so I don't know where people are getting it.

720-735-5376, 31-May-2017. The same just happened to me; 1st time from this number. However, my "Truecaller" app popped up a BIG "SPAM" redflag where it had 37 spam reports on this number.

called my cell phone and rang twice then hung up. I've blocked the call but I'm on the do not call list so that is annoying.

Called my cell phone.  Hung up after the second ring.  left no message.
