I did also today. Left no message.

One ring inly. left no message

Same here.  1 ring.  Called 2 days in a row.  

Got a call from this number 2 days in a row, one ring and hangs up... calls around 1:30pm daily
Has anyone tried calling this number back?

Some stupid company with rewards thingy. Called me a few times. I called back and pressed 2 to be placed on their "do not call" list, but I could have sworn I did this exact same thing last week.
