I used ziinga on 5th december 2011, I had won a camera in a free auction. On 31st december 2011, ziinga took £59.99 from my bank account without first asking me, I was not given any idea of membership when I first used it. Due to this I am £59.99 out of pocket, and have had to cancel a direct debit bill payment I was due to pay with this money. I tried using live chat on ziiinga web page, but kept getting ignored, I have sent them 3 emails demanding they repay the money, otherwise I will report them to the authorities. I may even seek justice via small claims court. People should stay clear of the ziinga site it is a con.
