Titan Eye Plus — Warranty on discounted frames

I have brought a Titan Frame on 5th Nov 2020 (Invoice #BXN0013269). The coating started to peel off about 7-8 months after using the product. I went to the nearest Titan Eye Plus store where they said there is no warranty on discounted frames. Is it because the discounted frames already have some dispute, and hence no warranty? Also when I brought the product I was not intimidated that there will be no warranty on discounted frames!

Desirable resolution: I am requesting a replacement of the frame.
