Black Jack Window Tinting

A few months ago, I decided to get my car re-​tinted a darker shade. It previously had a flawless tint job from the BMW dealership… just not dark enough to keep the heat out. I made the mistake of letting Blackjack talk me into letting them strip & re-​tint my car for $ 200.
After I got my car back the first time, there were bubbles galore from slamming it out & not cleaning the windows correctly. They claimed it was a windy day so dust may have gotten on the tint. Well, whatever… it looked like crap. Also the glare strip on the front was cut crooked… off by ¾ of an inch from left to right. The tint on the doors at the top weren’t cut uniformly… like they were cut with a butter knife. I know that wasn’t the case though as the installer managed to leave a razor blade on my leather driver’s seat which I sat on & didn’t see until the next morning.
I took it back & the owner said he’d fix it… well, not him personally but his installer. I gave them the car, they cut a new glare strip & attempted to get rid of the bubbles. This time, he managed to scratch the tint on the rear glass. He said it wasn’t the tint but a scratch on the glass… wrong. I swear, there were even more bubbles the second time around
I took my car over to Mike at Eco Tint & he said they wouldn’t even do that poor of a job on a beater Hyundai. He told me he could strip it all & guarantee no bubbles on the re-​tint. I went back to Blackjack & asked for a partial refund since I decided to go back to a place that had taken care of me properly in the past. The owner said he can’t issue any refund, but they would make it right. I asked him if he would tint it personally & was told that he doesn’t tint windows but has faith in his installer to do a good job.
Long story short, I gave it back to Blackjack 2 more times, they left another razor blade in my car (this time on the floor of the backseat where my passenger in flip flops found it) & I still have bubbles/​scratches but and not going to keep taking it back for the same results.
The owner is a nice guy but should have given a partial refund or full refund considering they did an awful job on the 4 times they had the opportunity to correct it. He needs to hire someone that is competent of doing the job correctly the 1^st time around. The install bay isn’t lit very well & this may account for the inability to see imperfections. The installer is a knucklehead & quality isn’t his main objective… speed is & it shows in the finished product.
I will have to go to Eco Tint to make this right when I can fit it in my schedule.
