Ninja Shark review for PreOrder Now Backorder WOD

It's been close to 1 week soon and we still haven't received a reply and the app is live not working as expected. There are all sorts of bugs, sometimes the orders are being tagged with the pre-order tags and multi-line notes, sometimes they aren't. We had to create a separate ticket for each particular issue and they seem that their devs are not working together. After many days, we had to hire a 3rd party developer and paid already a few hundreds of $ to fix big issues while still waiting for their reply. When we asked again, they said they send developer/collaborator request to get access. This after another member of their team requested and got access a week ago. So, I assume they haven't even bothered to check they already have access to the store. Not sure what happened, maybe the worst time of the month for them, but we really really wanted this to work. That's why we invested already a few hundreds of $$ to make it work at the minimum and hope they can fix the remaining. What is not working: - the preorder message is still not listed on all product pages (one some yes, on others no) - this has been partially fixed by our dev - the popup on the cart wasn't randomly displaying and once it was listed, you couldn't close (x/close button not working) - the pre-order tags are still not applied to all orders with out of stock items - certain items still do not show the out of stock note at the product level (some yes, some not) - we still can't edit the content of the email that's being sent if a product is out of stock to the customers (only the subject line) UPDATE to Sean: Hi Sean, I find that the following statement is 100% false: 'some themes which have been modified quite a bit do conflict with our app, and custom fixes have to be made by our team. But they CAN and ARE made if you let us know what is awry.' Your devs haven't made any proactive recommendation or change to the website. None I have provided collaboration access to your team from the beginning, and yesterday someone said they will send a collaboration request and if I can accept it. They haven't even checked that access has been already provided 1 week before. That makes me think your team haven't had the time to look over even once to our situation. That makes the following statement also false: 'Works out-of-the-box—no complicated theme installation or coding required' - it doesn't work out of the box and there is custom coding required Another false statement: 'Enjoy super-fast customer support—even available on weekends!' - nobody bothers to reply after I was told they will look into it and there were no replies during the weekend.
