contact E-bay. see if you can get info from them on the seller. can you find out where the pay-pal went? maybe cancle it or something? (honestly i dont really know how pay-pal works). good luck to you. hopefully they are just busy or out of town or something. have you tried emailing the seller? if it is a big seller with multiple listings maybe you just got lost in the shuffle.
