VERGE review for Carty: Add To Cart Button

I installed this app and unfortunately couldn't speak to anyone. I have sent 3 e-mails, but nothing. I want it uninstalled but again, can't find anywhere to uninstall it. Perhaps now, I need to reach out to Shopify and see if they can help me to have it removed from our backend. The App does not suit our store, the collections page gets too crowded. If there was at least communication or if we could find how to uninstall it would be ok, but we can't. Not keen to leave bad reviews but it may help other store owners.
