The call I got twice today within 45 minutes of each other was from 737-1998, Avantage pro po - - there's a company called Avantage pro portes et fenetres (aluminum doors and windows) in Montreal. The entire name may not show on the Caller id screen - lack of character space. Since I recently got an aluminum window fixed at another company, it's possible there's some sharing of client data between similar manufacturers ???

on my display...was not home to answer

Called for a proposal to have windows cleaned/looked at.I filed a complaint with CRTC, and so should everybody else: https://www.lnnte-dncl.gc.ca/plt-cmp-eng

This lady called for my mom, when I said she wasn't there can I take a message, she goes no thanks, and hangs up immediately.

these people are calling and hanging up, then calling back 5 minutes later.  a real pain in the backside.
