File an appeal with the App Review Appeal Board (or whatever it's called). It's pretty simple to do from iTunes Connect. Someone smarter than a robot will look into it and get back to you (my IAP appeal took ~14 days, but they did take precedent set by other apps into consideration and understood some nuanced arguments, so they might know what Stripe/Square etc are and how it matters)
