Screen Protector Defect

I bought my iPhone xs along with the $40 screen protector around November and two weeks later a bubble started to appear in the top right corner and day after day it kept growing so I took it to the apple store to get it fixed, the were the employees were very rude but they replaced my screen and told me I shouldn’t keep changing it just because of a bubble. Well the new screen protector started to grow a bubble in the same spot as last time and I tried ignoring it but it’s grown all the way down the edges of my phone. I don’t know what to do or how to fix it.
