Absolute worst service and ***** behavior

This has been the worst experience ever! I filled in the inquiry form online more than a week ago. Then all of a sudden I get 2 messages from random numbers asking for the measurements, stating they are vendors of PG Glass that gets the business from PG Glass when they are too busy. First of all, if I phone a specific company it means I want to deal with THEM, not someone random who claims to be a vendor - RED FLAG!! Then someone pitched days afterwards for 5 min, and left again saying they will come back. Never came back, never heard anything from them again! Tried another PG Glass branch then again, and same story, random people messaging my husband all of a sudden asking if they can come - HOW DID THEY GET HIS DETAILS if we have never dealt with PG before never put his phone number down as I am the one organizing these. Next thing you know, someone knocks on the door claiming to be from PG and robs you blindly!
