Purchased a hot water heater using their installation services. However, there were such poor reviews of the installer (Perez Enterprises) I called to cancel. Perez Enterprises told me that I had not been charged yet. Since I had not been send an order number or receipt via email so I assumed that was true. I then found out from my account that I had been charged. I had to call Home Depot customer service to get a refund but it took a long time because at I still had no order number or receipt. This process left a bad taste in my mouth.
