Scheduled for an estimate for 8 windows and possibly a bay window for our living room for today 1/10/2020 at 6:30 PM. My husband received confirmation call telling us they would be here. Well it s 8:15 PM and No Call saying they where stuck in traffic or can we reschedule. If you can t show up on time or even call saying we are running late or can t make it that shows us that 1 what would happen during an installation and two you don t want our business.
