You didn't say what expectations were set when you put your order in. This vendor makes custom made items, probably to order. That would typically entail a longer wait. I know of one person who dealt with them and were happy with their purchase.
The tracking number just means he probably purchased the shipping label, it doesn't mean it is on the way, but hopefully it is. If you really want the item, you might just have to wait until they send it. If you want to cancel the item, you might be able to do so with your credit card.
It seems like they have heard your complaint, but not doing much about it. That's a lot of money to have spent without getting your item. Good luck, and update your thread once you get a resolution.
