Casas Padel review for Shopify Marketplace Connect

It does not respect inventory rules or quantity. I keep getting orders for items that have been sold out or that are in locations that do not support online store selling. I have tried getting a solution from their support team and have waited for 3 months for a solution and they have stopped replying to me. I am a software engineer and understand why the inventory system is failing, and have explained to them in detail the use cases how to fix this. They have yet to get back to me since January. @Shopify can you find a better partner to fulfill marketplace connections or develop it yourselves?
