Phone going for 7th repair for the same thing

I had my galaxy note 4 screen replaced last month. It's been going bac to MTN for 5 times now they can't stop the screen from lifting so I took it to samsung and when I collected the phone today and the screen is even worse. Keeps lifting up I'm skeptic of taking it in for the seventh time now. One whole month to fix a screen? They replaced the screen then they replaced the frame and damaged the main board so they replaced the main board as well but still screen lifts after my 5 MTN visits they finally lifted their hands and refered me to hellopeter. What shall I do?
