Mega Fabrication refused to address issue

I'm writing to complain about the warranty service I received from Mega Fabrication. After paying $512.37 for membership, I found that it is not compatible as claimed. I've tried resolving this with your customer service team multiple times, including speaking with Liliana N., but have not received a satisfactory resolution.
