Rebels of the Future review for MagicPass Wholesale

I installed and it locked my whole website not the page I'd added for wholesale, so I lost a whole days worth of sales and it also stopped the shop app from working - still not up and running even after uninstalling. Theres no contact information for the app, the website link is broken, there's no way to contact anyone. worst app, shouldn't even be allowed to be on the shopify platform.
