I am dissatisfied Amazon

The product is excellent. Samsung thank you.
But I am not satisfied with Amazon for the first time in years because the product before ordering was 25.23 gold after order, it is 10.06. 24 hours!
This is the same product as the top of the page, the site tells me I've already purchased the product.
A joke on you? I had total confidence in Amazon and I'm a disappointed customer.
I would have to tell someone Amazon rather than going through the assessment, but at least one human will read this message.
So Amazon customers, be vigilant because this type of practice is disrespectful customers that we are.
Amazon, and if you continue, you will lose what makes your worth: your customers.
