There are many alternatives for PayPal; stripe being one but there are many others as well that won’t totally screw you as merchant like PayPal does. I use a local one who actually defend me when there are chargebacks and I can visit and talk to a human in case of other issues.
+1 for using local providers for critical infrastructure, especially financial stuff. If something like this happens to me and I can't achieve anything through support channels (which is already unlikely), I can get on a train and go bang on the provider's door within 3 hours.
