Account Frozen Without Warning

As a business owner, I used paypal to conduct e-commerce transactions for custom-order products. Paypal one day without warning froze my account (allowing no withdraws or purchase to be made) asking for my supplier’s information, business documents and tracking information on 5 of my clients orders before my account would be restored. I called paypal to inform them that the nature of the products being custom meant that they would take several weeks to complete. Paypal did not care. Upon  submission of the first 2 tracking numbers paypal FURTHER restricted my account barring my ability to request and receive money which cost me almost 2 months worth of business. The final tracking number was submitted last week and my account status is still pending.

What gave paypal the right to restrict my account when there was an existing agreement between my customers and my company and NO COMPLAINTS from my customers?
