Who called from 4126649989

Number called twice, with merely 30 seconds between calls...and nobody is on the other line when answered.

said they were from FOP selling circus tickets

The phone number called @7:42 pm Friday (7/24/2015;tonight), hung up on me as I answered ; I called it back & it just  rang with no answer, no voicemail when I tried calling it back .

Got several calls from 412-664-9989 no message left.

Rang my landline yesterday while I was out. Had I been home I may have answered as this is my local area code, and even the exchange is relatively local to me. Glad I didn't as it appears to be a spoof or spam line.
