Professional Window Tint

Gave me a window tint 3 years ago, the back window is now covered in air bubbles.
I have a lifetime warranty.
But he wont answer his phone ever.

DON’T WASTE YOUR TIME!!!
This guy really doesn’t know what he is doing, although he SAYS «I’ve been doing this for over eight years».
Where should I start?
First of all the rear window had lots of little bubbles which he tried to fix but couldn’t, also the film wasn’t even sticking to the windshield from one side (had to go a second time for him to fix that).
The front side windows had some bubbles and lint from the rags he uses to clean the window,
The quality of the film (Soltek) sucks! My windows look all wavy, he even did the front twice to see if it would fix that problem but they turned out the same maybe even worse.
Bottom line, save your time and multiple visits. I going to end up removing the cheap film, loss of $ 150 and have someone re do them the right way.

This place is horrible practice.
1) Although the guy said it’s lifetime warranty, however, he said he would only redo it if the bubble is bigger than a nickel size. I had my car done there and there are fingers crease along the rear windows and the guy refused to fix it.
The worst is he told me to go back in a month to have it fixed. And I called to schedule another appt after a month. He told me honestly he couldn’t do a better job and he said he doesn’t want to waste «our time». He said those creases are normal and the best he could do!!! He’s just wasting my time in waiting for a month to come in.
2) Plus, the quote was about $ 170, it ended up to be $ 170 plus tax and CASH ONLY.
