Amazon customer service is TERRIBLE!!!

I placed an order for an item on 5 Dec with a delivery windoe of 5 days. By 15 Dec I had not received my item nor had I heard from Amazon. I phoned them and was told the item was supp**** by a 3rd party and they were not responsible for updating me on any delays. They told me I must contact them again in 48 hrs as that is the turnaround time for the 3rdparty to reply to their query. I spoke to and agent who said the supplier was out of stock and it was the suppliers responsibility to have informed me. I paid Amazon for the product, NOT the supplier. I asked the agent where my money was and she said she did not know!!! She told me that they are in the process of removing the supplier from their books (which I later found out from a supervisor that that was a lie!!) They offered no solution but to cancel my order. Now I have to wait till they contact the supplier and to get my money back from them before they can refund me!! So who knows how long it will take to get my money back so I can buy the item from another supplier!!!!! TERRIBLE customer service!!!!!! Very unhelpful!!!
