Surface Restoration Service LLC Will not honor warranty of failed work Lancaster Pennsylvania

I was told I had a 5 year warranty when I was quoted the work by the owner David Selfon. The work was done in April 2013. The tub started peeling after about 18 months later. I called David and he had me take a picture of the peeling and send it to him. He immediately called me and accused me of 'allowing my kids to put suction cups on the tub". I don't have kids nor have I placed anything on the tub other than a shower curtain. He never inspected the original job his employee did nor was he willing to honor his own warranty. He also said his employees can't read or write and his warranty does cover use of suction cups (which I never used. I paid $325 for shabby work. Very unprofessional.
