Daniel's Automotive Window Tinting

Had my windows tinted a few months ago. Noticed today that there was a small section at the top of a window that had come off. I called and the first response was " I don't recognize you or your car, can you send me pictures"? I sent pictures then sent a task asking when I could bring my car over. He called and said " how did you do that". I replied that I didn't do anything and that since calling I noticed several windows with small "bubbles". He said his warranty was only good for the film and he didn't work for free. He had a really bad attitude and I responded with maybe you can talk to my lawyer. He said that's fine, have him call me. He blocked my number then continued to send me texts lecturing me on my behavior, I couldn't respond since he blocked my number. He threatened legal because I was slandering him. All I wanted was for him to look at my car and stand behind his workmanship, I guess that was asking too much.
