My paypal account was permanently limited??

Today i decided to start selling clothing and I needed to do it thru invoice on PayPal so i send invoice of amount 110€ and i recieved only 103€ then paypal said i need to do a verification? I did it and I explained i want to just sell clothing but the problem now is when i checked my PayPal after 5 min they say : You can no longer use PayPal as we have decided to permanently limit your account after a review. Like what that mean???? i was using paypal for year without problem but only F&F. What im supposed to do now? I just hope my account will not go to negative balance when i refund the money to the buyer. Can someone please explain why they blocked me or what happened? And what to do now to just refund the money without being in negative balance. Please.
