Dropped off a snowblower at Home Depot for repair, and while I was in the store this number called my phone. Pretty sure it is a legit Home Depot number, but can you say annoying to get a call before I even leave the store? That's nuts.
I'm in Wisconsin, too, and it was a Home Depot in Wisconsin, so Georgia must be where they have their call center.
If you never put in an order and are getting these calls, someone may have given Home Depot a bogus number so they don't get all these annoying calls, or the store employee may have input the number wrong and your number is what was put in there.
