High Value Target review for The Shop Events Calendar

I must have some skills because I built the entire website and I've been taking orders for 3 years. I also downloaded EVERY EVENT CALENDAR app that Shopify has listed in the store and I couldn't make even ONE WORK! I'm pissed. There isn't even ONE event calendar app that a small business owner can install without help. I did however, enlist the help of an app developer and after wasting another 3 hours on that tech-chat I gave up as the developer couldn't seem to figure out the problems. There is no embed code or method to get this app installed onto my Shopify store. So much for the "Shopify" app. I'm having issues getting it onto the page that is already online. Also, I can't find any controls for the app to input a date or event on the Calendar. The app isn't "verified" so the branding content remains at the bottom, they know who they sold the app to? Verify? Ridiculous. At this point I'm more pissed at Shopify than a dozen different app builders because SHOPIFY doesn't offer a realistic solution to a very simple request; how about offering a simple Event Calendar that ACTUALLY WORKS!
