Simple In Store Pickup

I would give this app a 5 star review but is does not integrate with ShopPay and PayPal payments. It was easy to install and easy for customers to use, but does not fulfill my needs because of the lack of integration with all payments.

TLDR; app was fine but very disappointed in the service. I installed the app and it worked okay, it just didn't do everything that I needed it to do so I uninstalled it. It left behind at least some residual code because I still had a product and vendor in the system from the app. I deleted the product but could not find a way to get rid of the vendor. When I contacted shopify support, they recommended I contact the app developer because its was their coding that was left behind, but when I contacted the app developer they insisted it was not their code (even though it was installed from their app) and they couldn't help. Update to reply:
Seeing as how there was your product left over in the shop, I don't understand how you can say your app uninstalls everything. The vendor did not disappear when I deleted the product, which is why I contacted you to begin with. It was still your code that left the vendor there. I have since solved the problem without your help, but thank you for your response.
