If the transaction OP did through stripe was for a product(s) containing CBD/THC (EDIT: They sold a van. > We sold a cheap van in the company name. ) then I can understand why Stripe closed the account as it’s on their restricted businesses list (often not because stripe disagree with the product, but the providers stripe use disallow them and stripe have to do so otherwise risk losing access to the provider for everyone). And once the account is closed there won’t be any more transactions on the account to recoup the cost if transaction’s get reversed down the road.

But that doesn’t excuse Stripes lack of communication / canned replies. Even if you are parting ways with a customer it’s not wise to burn bridges, who knows maybe CBD/THC products won’t be shit listed later down the road and you would welcome the customer back. But leaving a nasty taste in the customers mouth will make them much more hesitant to return.
