Hello,
I am not sure if I am writing this to the right place, hopefully I am.

First of all, I have many Acer products and I am satisfied with most of them except my monitor... I purchased an Acer XB271 HU A Predator at the end of 2016 (which I thought is a premium category monitor with premium support...) and I have been very happy with it until a few weeks ago. I haven't played any games for many months now and I have been programming and studying a lot lately with the default settings of the monitor. It turned off after 10 minutes of being away from keyboard. Long story short, it happened that my windows 10 taskbar burnt in the panel (not sure how, this shouldn't suppose to happen in 2018 as I know?!) so I have called the local Acer customer support team who "helped" me out returning it.
I just got it back from the Checz service a few hours ago and realized that nothing has been changed on it and it has absolutely the same panel with the burnt in taskbar as before. The service report that the Acer customer support guy filled out it says I reported "brightness/darkness issues" which is obviously not true. The service returned my monitor without fixing or changing anything on it... I do not think it's fair that I spent around 800 usd on a monitor and nobody gives a **** about my warranty.
Here is a picture of the problem I'm facing with the monitor with looking at the footer of the Acer's website - there is a burn mark on the monitor where my task bar is, going all the way across the bottom portion of my monitor. Sorry about the quality I have my phone camera available only:

Best regards,
Peter S.
