WooCommerce Subscription and Payment System Review

I'm looking for an experienced WooCommerce developer to investigate subscription and payment issues on my Craft Box Direct website. Problems include customers being incorrectly charged after cancelling subscriptions, Incorrect Stripe payments which did not generate WooCommerce orders and incorrect automated customer emails. The website is also still connected to the previous owners' Stripe account, which will eventually need to be migrated to my own account. The initial task is to review the current setup, identify the causes of these issues and recommend solutions.
