Everyone suggests calling, but you can also contact them via mail. Their response time is actually fairly good, though of course if you need an answer right now and you can't wait 24 hours then I suggest you try contacting them via Skype. Still while you are figuring out what to do I do suggest you send a mail with your inquiry.
Also OP have you sent money before? Asking this cause I believe that some countries can "pay" for things, but can't send money. If this is your first time sending money it might be a good idea to check if your country is among those countries.
Note: I'm not entirely sure if PayPal removed that limitation or it still exists, but I do remember a year or two ago encountering a client who couldn't send money, but could pay if there was a "buy button".
