Amazon.com Bait and Switch

I’m hoping that someone may be able to assist me or at least look into this situation. I’m dealing with a bait and switch situation with Amazon.com and at this point I’m getting absolutely zero assistance from their own customer service. I purchased an expansion pack from Amazon. It was available from Amazon, not their “sellers, ” and they advertised it for $9.99 plus shipping. As of October 25th, my order had still not even been shipped. I contacted Amazon customer service, via e-mail, and was told that the product is not available through Amazon and that I would need to cancel my order and purchase it from one of the “Sellers” on the Amazon product page!
