Complaint Review: Home Depot

I purchased a suite of Samsung kitchen appliances (range, over-stove microwave, dishwasher, and refrigerator) from Home Depot on 5/27/2020. My original delivery was scheduled for 7/14/2020. I was later notified that my delivery was delayed to 7/29/2020, and later that it was delayed again to 9/2/2020. I understand that manufacturing and shipping are delayed due to the pandemic, but I called their customer service number to try to get a better idea of the status of my order. They then informed me that the range I ordered was no longer carried by Home Depot and no longer manufactured by Samsung. I asked when they were planning on telling me this and they had no answer. I asked if they would substitute a similar range and they said they do not do exchanges or substitutions. I asked how this even happened in the first place, because I had checked their website many times while waiting for my order and saw the appliances go in and out of stock. They told me that online orders are sent to the nearest physical store to process, and that store moves online orders to the back of a queue. Customers who come into the brick-and-mortar store are given priority. So, if available inventory is purchased before my scheduled delivery date, my delivery gets pushed back. Usually this isn't an issue, because Samsung (or GE, LG, Frigidaire, etc.) is able to ship out more appliances to cover this. Now the pandemic is exposing the shady way that Home Depot has been conducting their business. They took my payment upfront and never bothered to secure the product that I ordered, and sold it out from under me to the next highest bidder. I've been making payments for 3 months now on a credit card for a purchase that I will never see, and Home Depot is not willing to do anything to make this right. My only option was to cancel my entire order so that I can take my business to Lowe's.
