Purchased a window ac unit on my Home Depot card on July 13 which turned out to be defective. As I was out of town my grandson returned the unit on July 21 with the original receipt. Without any explanation the cashier gave store credit instead of crediting my Home Depot card. My grandson even talked to the store manager why this happened. He didn’t have a clue. After I made numerous calls to customer service, calls to 2 store managers, and numerous emails this issue still has not been resolved. No one seems to have a clue on how to resolve this issue. Get your act together Home Depot and train your employees to better problem solve simple situations like this. Will be closing my account so I do not have deal with incompetent employees such as yours anymore.
