Unfortunately, this is far to common with Stripe. Stripe shut down my previous SaaS without warning or explanation, and later turned it back on after admitting they accidentally shut it down. It was almost a death sentence for my business.

I built OpenPay (getopenpay.com) so you can flexibly move between payment processors without losing a cent of revenue. Happy to get you set up for free, and help you migrate from Stripe. Feel free to reach out to me at lance [at] getopenpay.com
