I doubt they responded to you, dude, I wouldn't count on it. They have a lot of orders right now. You have to wait for a response even after payment. I recently placed an order and waited almost 3 days, dude, can you imagine, almost 3 days!???
Don't confuse this with the Amazon store, where there are a lot of employees. Most likely, emails with regular questions are completely deleted, the priority is to contact those who have already paid. It's true, dude. A legitimate seller always has a lot of orders, and on the darknet, this means that the response time will be very long.
