Would give zero if I could

UPS lost my package. The service person said if it is deemed to be lost then they will submit the claim to Amazon and it will then be shipped via UPS with no intervention required from customer. Now they concluded after investigation that it was lost, now no claim has been filed and they tell me I am supposed to do all of their work for them. With no additional information on next steps or even how to contact Amazon....Just a "go away it is your problem now" attitude.

They also don't care that I would not be able to get the item anymore if I need to order it myself again, as priority shipping is not available. So now UPS sits with my money for shipping and because they have the money, they don't care anymore what happens.

They keep on contradicting themselves and straight up lying to me as well about what was said. No clarity on what is supposed to happen next. Some of the worst customer service I have ever experienced.
