You didn't explain it very clearly? Have you already made an order or are you just going to?
There is not much information about this site, but many people here have written reviews about how this sometimes happens with different legitimate sellers. Sometimes you have to wait a long time for a response, confirmation of payment or receipt of the goods themselves. I think there can be many reasons for this. You need to focus and wait.
I don't know if this site is legit or not, maybe you were unlucky and were deceived. Still, you should hope for the best.
