Refund refused by Quality Community Nizhny Novgorod

I'm writing to complain about the support package I received from Quality Community Nizhny Novgorod. After paying $665.50 for item, I found that it encountered rude staff. I've tried resolving this with your customer service team multiple times, including speaking with Mathilde H., but have not received a satisfactory resolution.
