i was in your situation once... all u can do is tell them that if they dont give you any further information that you are asking for that you will report them to paypal, and what will happen is paypal will send them a bill that they have to pay or at least respond to. if they dont respond, then paypal will give you your 2600 back and bill them. after they bill them those people will not be allowed to use paypal or sell anything online untill they pay back paypal. so go ahead and tell them that if they dont give you the info you are asking for, you are going to report them to paypal, but all in all tell them that you have been given no choice, and be kinda nice about it, they should do whats right. Good Luck with this
