These guys are driving us crazy.  They call 2-3x/day and claim to be HVAC services.  Have asked repeatedly to be removed from their list at which point they hang up - repeat.

Given the 123 exchange I imagine this is a total scam.  BTW, when you call it back the number is spoofed, an obvious sign.

Not sure what their scam is but I'd stay FAR AWAY from these people!!!
