Who called from 2062283067

i have received several calls from this number over the past few days. I picked up a couple of times but the call is terminated by the other end. I've blocked them.

They keep calling but never leave a message.  Sure sign of a scamming, spamming telemarketer.

Calls many times and doesn't leave any message. When call back, it's not in service

They call claiming to be from Vortex Heating and Cooling (or Vortex Heating and Air).  They claim they are having a duct cleaning deal and technicians are in your area.  They keep calling you even after you ask to be taken of the list.  Essentially they harass you until you give in.
This is a scam. Different people each time and they try once a day.   Beware of anything offered from this caller.

pissing me off, they call at leas once a day, i don't answer, they don't leave message. Stupid AT&T doesn't allow blocking on my phone.
