Home Depot deceptive advertising- bait and switch Spanaway, Washington

Home Depot advertised LG appliances on sale. We are doing a kitchen remodel so we purchased a range,dishwasher,refrigerator, and over the stove microwave. The store checks inventory then allows you to pick a delivery date that is convenient, and is susposed to call the day before to confirm. They do call the day before, but to tell us that the microwave is on backorder so they are going to hold the whole order until it comes in- estimated to be 3 weeks. I call customers service to see if they can still deliver the other 3 appliances (as we dont have any) and was told that now the entire order is on backorder with an estimated delivery of 6 to 8 weeks. I go to the store to talk to the associate who assisted us with the sale to ask what is up. She was very helpful when she said " well you got such a good deal what do you expect, you will just have to wait" I contact the store manager  to ask what our options are, he says we can resellect a different brand and pay the difference- sounds to me like a bait and switch- advertise something you dont even have to get you in the store then try to sell you up. A few days later the manager sends an e-mail telling us how sorry he is, and that he has arranged for them to deliver the 3 appliances right away. He tells us to expect a call to confirm delivery the next day. It has been  a week and we are still waiting for that promised call.
