Home Depot - Richmond

Purchased a new dishwasher at Home Depot Richmond; good price, on sale. Then had to wait 2 weeks for delivery and installation. On the day of delivery, two technicians arrived and got the new dishwasher partially installed, but discovered our plumbing was too old and incompatible with the new machine. Unfortunately the two guys who were there were not "allowed" to do the plumbing part - I would have to call Home Depot and arrange for someone else to come do that part, and they would be able to finish the installation. his meant me having to take another day off work. I paid them up front for this additional service and then they left, neglecting to tell me that I couldn't use either the dishwasher or the kitchen sink to do dishes (which I discovered when I tried to hand-wash some dishes and ended up with water all over my floor). The next morning Home Depot called me to verify the additional charge; I asked when I could get the technician to come out to perform the plumbing task, and the woman was surprised, thinking it had already been done. She then supposedly booked a technician to come out "between 10 and 2." After 2pm came and went, I called and was told I was "next in line." Then 3pm - he was on his way; at 4pm I was told that the dispatcher couldn't reach him and didn't know where he was. He assured me that he would do his best to get someone to come out that day - it was a Friday, and I didn't want to go all weekend with no way to do dishes. Around 9pm, the SAME TWO GUYS from the day before showed up, plumbing part in hand. They were very efficient and in short order had the new valve installed and the dishwasher working, the very thing I had been told they were unable (not allowed) to do. So finally the dishwasher was in, and working, but it made me wonder why it couldn't have happened the day before. In short, can't recommend Home Depot as a place to buy a new appliance.
