Hardware Right analog joystick drift, even after repair

[medoli900]

My PS Vita right analog joystick was drifting to the bottom left when I bought it (used). I tried the rotating clockwise/anti-clockwise many times, tried to dust it with compressed air, tried to disassemble the PS Vita and dust the joystick with compressed air. So I bought a replacement joystick on Amazon. Wait almost 2 month and got it. Replace the joystick, still drifting, but even worse. (The new joystick even looks worse than the old one) I retried the the rotating tricks and dusting, still nothing.

What can I do now?
Should I file a claim on the seller or is there something else that I don't know of that could help?

Edit: I should have said replaced instead of repair.

Did you try rotating when in systemsettings?
Thats what was mentioned in old psp-manuals. Maybe it helps for the Vita too.
Cant try it, since my Vta works flawless atm.

I filed a claim and got the money back. Yes, I did try the rotating tricks, it doesn't works. I'm waiting for Ifixit to restock on Vita Joystick, but it doesn't seems like they will.
