Warranty claim denied by Solid Engineering & Sons Kazan

I'm writing to complain about the exchange program I received from Solid Engineering & Sons Kazan. After paying $179.15 for application, I found that it doesn't work as advertised. I've tried resolving this with your customer service team multiple times, including speaking with Cindy Z., but have not received a satisfactory resolution.
