True Customs Bad Tint Job, National City, CA. I just wanted a refund.

I had my windows tinted on my car on 9/25/18 by a company called True Customs. I had them tint previous cars without issue. However, they did a horrible job on my 1998 Lincoln Town Car. I brought the car by the next day to point out three major defects in the tint job. The back window nearest the third brake light and the two rear 1/4 glass windows nearest the top corner. Abel, the manager said that they were to busy to look at it and to come back the following monday. I had other commitments and became available to have them look at it again today 10/11/18. I called at first to let Abel know that the tint had lots of small bubbles on every window and that the tint was not acceptable. I requested they remove the tint, refund my money as I would like another company to install the tint as it doesn't appear they have a skilled installer. He said he needed to look at it first. I drove down there to show Abel and he said that it was an old car and that's just how they are. Made up excuses about the rubber window seals causing the bubbling. Total BS, I've had many cars tinted and know the difference between a good tint job and a bad tint job. I again requested they start the refund process which he told me would take 14 days and that I would bring the car back to have the tint removed and obtain my refund at the same time. I've already made 4 visits to the shop all on my time/dime and haven't been able to resolve the issue. Abel referred me to the "contract" that I signed when I got the car tinted. I believe the "contract" is a two way street and they should have made good on their tint job. The "lifetime warranty" isn't an issue with the tint material, but with the tint installation and what appears to be improper prep and cleaning prior to tint installation. He asked me to come back on Monday again, but I do not want to go back again and have to deal with Abel without being able to obtain my refund. I don't think it's unreasonable to ask for a refund on this as the work was not worth the price paid, irregardless to the vehicle value... a $200 tint job (discounted to $180) should still be a $200 tint job and done at a professional level as they make it a point to advertise they do tint starting at $89.
