missed calls all hours of the day and night from this number with no message left. I finally answer the call. he starts in right away about the weather without introducing himself. he says that they will be coming out to test my water, as i had filled out a water sample and sent it in. (back story: at home depot, they had a stand with self-stamped water containers. the envelope said to fill out the information, fill the container with water, and get a $20 home depot card. so i filled it out, sent it in, and now all the phone calls). he said that the water i sent was just used to calibrate the machine (and yet he told me my water was fine) and that they would be coming to check my water. i told him no he wasn't, and that they could mail me the results along with the giftcard. he mumbled something about the small print. i told him this was false advertising and he said that there is a clause on the envelope. i told him that he wasn't coming to my home, and never to call me again.
