How to sue a person who don't want to refund or give the units I bought?

Aug. 15, 2013, I have bought an iphone unit to my friend's friend. Her name is Aish Alagon. She made me pay 8, 000 on her bank account as a downpayment for 2 units of iphone. She promised me that I will be receiving the unit on Aug.31. On Aug.31, She said that the units were on hand already and will be given to me on the 1st of September. Sept. 1, She said that the units are on her supplier and will be delivered to me on that day. The delivery date was moved for several times due to different reasons. Sept. 25, she made me pay an additional 14, 000 so that I can receive the units on the same day. But still, no units were delivered. Until now, Nov. 19, I don't have the units nor the refund of the money I gave her. What can I do in this case?

You fell for that? Your screwed unless you had a signed contract. You paid 22, 000 for two units for resell? Not only that, but you paid 14, 000 after she failed to deliver the first time around? Go to court but there isn't much you can do without a contract

Short answer? She played you. And scammed you.
