Amazon order problem

I ordered on Amazon on August 31st.
It is now October 20th and I still have not received my item.
The person just keeps moving the shipping date back and he put it as already shipped so I can't cancel the order.
Live chat is no help at all, they just keep giving me bullshit answers.
What am I supposed to do with these retards?
It feels like I'm talking to a chinese gold seller now.
Here's my Live Chat log with them:

I ordered something and I have not received it after a month and a half. The date of delivery would keep changing.3:20:59 PM
Guruswamy:Hello Feng, I'm Guru. I'll be happy to help you. 3:21:07 PM

Guruswamy:Items listed as "In Stock" typically take up to 24 hours to package and prepare for shipment, but can occasionally take longer. As you may know, we have several fulfillment centers across the U.S., and the items in your order may sometimes be in stock at different locations. When you place your order, we estimate your ship date based on where we have inventory, the delivery address you provide, and how quickly we can obtain and assemble items for shipment.3:24:42 PM
Me:I ordered this on August 31st, it is now October 20 . . . 3:25:09 PM
Me:How much longer do I have to wait?3:25:13 PM
Me:If I ordered an item, I expect it to come 2 weeks max, it's been more than a month.3:25:31 PM
Guruswamy:Some times we're unable to receive the items from our suppliers, so we'll ship your order once we receive the stock from them.3:28:17 PM
Me:What do you expect me to do? It's been more than a month that I have been waiting for my item!3:28:43 PM
Me:I want a refund.3:28:50 PM
Guruswamy:I'm sorry, your order has entered the shipping process and we're unable to cancel this order for you. 3:30:14 PM
Me:What can I do then?3:30:29 PM
Me:It's been MORE than a MONTH

 

I believe you can contact Amazon to help you resolve this.
