Called and said that I filled out a water softener survey at Home Depot in Yulee Fl which I Had not. They did the same to my mom and grandma. Scammers!!!
The caller said they were from Home Depot and offered to the water quality at my house. They said it would take about 45 minutes, and I would receive a $25 Home Depot gift card afterwards. I asked them if it was a water softener sales pitch, and they said "No".
I subsequently called Home Depot and inquired if they were familiar with the caller. The staff member said that Home Depot does give Rain Soft (?) leads (typically after a customer makes a water-using appliance purchase) for water quality testing, given that FL's poor quality water. They will test the water, and provide information and pricing for (water softener) systems to improve the water quality.
