Who called from 7205246947

Caller left no message.

I'm on the DNC list, so if this is a sales call, it's illegal.  I have no business relationship with this company.  

Perhaps it was a wrong number, or spoofed - I have no way of knowing.  I will not do business with this company, irregardless.

This company calls often; about 6 times a year. They are offering to have one of their technicians, who just happens to be in your area, to inspect your furnace, free of charge.
They change their phone number often, so I have to keep blocking them
