Razer Raiju Ultimate - Unbearable Stick Drift

The stick drift on my razer raiju ultimate was such that it didn't have a problem in most games (I checked it on the games I had when i got it: Assassin's Creed Unity, Fortnite, Metal Gear Solid V, FIFA 19). But since I've started using it regularly on my ps4 it has become absolutely unbearable. I use the following gamepad axis visualizer: http://www.wmchan.com/info/gamepad/index.cshtml Using this, the right analog it used to give me a stick drift of 10.54% to the right at max - which was fine for most games as it was covered by the default dead zone settings in games. Now, the maximum it gives is 36% to the right and it sometimes locks itself around the 20-23 % region (See attachment). Also, at times there is horrendous input lag in PS4 bluetooth mode and I have to reconnect the controller to the ps4 to fix it. My question is how can a controller that costs 200 euros be made in a way that after 5 or 6 months of use it has become unusable? What is the quality control policy at Razer? You charge premium price for products and besides decent rgb you ship them broken? I got this controller in Germany and am currently using it in Pakistan - but I need a replacement as soon as I go back to Germany. This is unacceptable.
