I get calls from this number as well, I never answer it. They also use the number 780-111-2233 - notice it's the same number with the exception of the first 3 digits.......both have been blocked on my phone.
Idiot duct cleaning service people call me almost everyday. I asked them
several times to put my number on their do not call list but the calls keep
coming.
From now on i will give them a fake address to send their duct cleaners ,
that's if they are a duct cleaning service. Could be a scam.
