"THIS IS A SCAM! They took our deposit and ran! Four Seasons sent over a 'salesman' who lied to us to get us to hand him over a $9000 deposit to build a sunroom on the back of our home. We were worried about fees and zoning issues with our town, and Four Seasons kept telling us all will be okay. But when our town raised zoning issues, Four Seasons refused to rectify the issues, and stop returning our calls and emails. They have ghosted us with our deposit and have not delivered any service. This is a SCAM! DO NOT HIRE THEM!"
