LG 27GP950-B 27” Gaming Monitor

I was hoping to replace my iMac 2019 with a newer Mac Mini and chose this monitor as a display. All the descriptions and specifications on various sites said that this is one of the best monitors and alternatives to the Apple Studio Display. As it turned out, it is a low-quality alternative with weak backlight brightness and low 4k. After the iMac 2019 Retina, this monitor turned out to be not what most reviews on the sites wrote. I saw this immediately when I turned on this monitor. I asked the seller on Amazon to return the monitor because it did not suit me. I received a code to return the display, but when it arrived at the post office they said that I had to pay a return fee of $ 63 I refused and wrote to the seller about this problem. The seller sent me another postal marker with free shipping. 5 days after the return I received a refund but they took a payment of 20% of the cost of the goods ($ 88). When I bought this, it was not indicated anywhere on the Amazon website. So I am very upset that I was deceived and was not given the right to a full refund. I think this is unfair and I will write to Amazon support so that they can help me with this issue.
