eCommerce Negligance - No reply from company

I've been trying for years to integrate TCG with a WooCommerce website, but support has been unresponsive, and my emails go unanswered. Now, we're facing issues with the PUDO app on Shopify, which hasn't worked since the latest update. Despite numerous complaints on the Shopify app store, there's been no assistance from the company. It's disappointing, especially given the current demand for online shopping, that a company of this size hasn't addressed these issues.
