Bought a phone off ebay and it is hassle as the seller is being awkward. Didnt send the sim card as advertised and is saying i'm hassleing her about it. Without the card (which I can replace) it is still a good price. I am concerned that if I leave negative feedback as I intend to, she can contact Orange to block the phone. I have unlocked th phone BTW to use on any network, but could she still cause me problems?
