If I could give them a score of zero, I would. We ordered windows and a sliding glass door to be replaced in preparation for selling our home. We have 11 windows, but only 10 were ordered. We paid for 11 windows and a sliding glass door in June. 10 windows were delivered and eventually installed 8/23/22. We have been battling with Lowe's over the 11th window, being told repeatedly we only have 10 windows, and if we want another window, we need to pay for it. The salesman eventually admitted to making a mistake and said a window would be ordered. It has never been ordered. No one from the local store (N. Peters Rd, Knoxville, TN) will return a phone call as promised, nor does their corporate office return calls or try to resolve the issue, who we have called many times. Customer service is terrible, disrespectful and an attitude of "who cares." It is now 12/30/22 and we still have no resolution on the window they miscounted and failed to order. They have repeatedly attempted to make it our fault, but we didn't place the work order that listed 10 windows rather than 11 windows, nor did we ever see any work order. Now we are told that the installers have to measure the window before they a place another work order. That window has been measured and remeasured. Their response is not to pick up a phone and call, but to send an email to the installer, or so they say they will. At this point, I will never believe anything that any Lowe's employee tells us. It is absolutely ridiculous to still be dealing with this issue after so many months. The next step may well be legal action. We will never buy anything from Lowe's ever again, not even a nail.
