I did not answer call.

called and hung up after two rings -- did not call back -- this is trash behaviour

Called on my cell phone.  Have no idea who this may be.

Called my cell & hung up before the first ring finished, no chance to answer. (Not likely I would have anyway since I don't answer unless I know the caller).

Had a "missed call" on my iphone from this number. Didn't recognize it, and no message was left, so I did what I always do with numbers I don't know...I googled it. As expected, others have received calls from this number as well. Guess I'll be adding it to my long list of blocked numbers. :)
