Rang it back, but it goes straight to end call. Prank I guess

received a call at work from this mob a few minutes ago. Based in Qld this is a new company ABN information company registered around May 2016. Promoting as a second income stream - $3 to 5 K per month. I smelled a telemarketing rat and have blocked this number. A quick internet search for Exelon has returned results but don't have the luxury to look in to it further

Nobody there then hung up

Rang but no one on the other end and then hung up
