hi i bought a spy on ebay . seller shipped 6-4-07 through royal mail signed for delivery. no bag yet to date. when i try the tracking number it just says its been given to the us postyal service. how would i contact the us postal service to see where my bag is? the seller just keeps saying be patient. i opened a dispute with paypal and don't want to do a claim when the seller has given me info but i am afriad i'll get stuck. any ideas of what i should do or who to contact?
