Post on BBB website, send the details and all relevant information to whatever your equivalent of the attorney general is and the one in Paypal and OVH's jurisdiction. Your best course of action is not to focus on PayPal but OVH. Send certified letters to both PayPal and OVH informing them of your contacting of the attorney general. Send to corporate offices and address of general counsel.

You can open arbitration but it costs money.

Be sure to clearly state what happened, why you think it is wrong, and your preferred remedy.
