This number is being used by RainSoft, a water filtration company, that offers free water tests through Home Depot, though according to Home Depot is not affiliated. First they report that your water is unsafe and they have to come to your home to further test and all of you need to be there, during which they try to pressure you into buying a $400 to $500 water filter system. Not a scam per se, but high pressure sales for something you most likely do not need and certainly don't want. Evidently, Home Depot is investigating consumer complaints about this company's methods. If you see the free water test display in Home Depot, ignore it.
Call was made to my home phone at 5:28 PM on 7/29/2016. Caller ID lists VICTORVILLE CA as caller. I know no one from there and have no idea why a city would call me so I did not answer and caller left no message. I have not been to Home Depot in almost 3 years so they must be using other sources for numbers to call.
