Alsph Window Tinting

Although Alpha Tinting seems to have a good product, their business practices are less than ideal and unprofessional. They showed up at my home about an hour late. What they were driving was a small beat up pickup. There were 2 men, father and son that did the installation while a girlfriend sat in the cab of the truck. I was assured at the time that I booked the appointment that I would receive a written warranty. I did not. I've tried several times to reach the business without success. Phone numbers that I have found online either have been disconnected or are the wrong number. I've sent 3 different emails to them with no response.

What are they hiding???
