i wanna buy something from amazon and get a refund of the product.

What Item do you wish to SE?

i actually want a samsung S8 ultra tab and then SE it.

There's a range of methods that are successful with Amazon. Have a search around the forum and look for:

EB - Empty Box
DNA - Did Not Arrive
FTID - Fake Tracking ID
Boxing

This should help you understand the steps you need to get a refund from Amazon with a little practice its usually quite easy.

Anything other questions just through them out and I or others will no doubt help you.
