Delayed delivery from Mart Express

I'm writing to complain about the support package I received from Mart Express. After paying $269.51 for product, I found that it doesn't work as advertised. I've tried resolving this with your customer service team multiple times, including speaking with General H., but have not received a satisfactory resolution.
