Really sorry for your experience, they don’t make any sense… For what it’s worth, I like the design, but the initial load was a bit slow.
My project https://omnicartshop.com got rejected the same way… no response whatsoever.
When I contacted them through support, they got back to me that they do not have time to give feedback, because that would require them a whole team… which doesn’t make any sense. For me even a 3-4 words sentence would’ve been enough, or just them having a dropdown select when rejecting for a general message.
The cherry on the cake was when at the end of the email it stated that they whish me luck on a future project though… This hits hard when you pour your soul into your work.
So yeah, it’s pretty much a joke.
