Fraud. Can't witdhraw

I aplied for withdrawal of ￥14,3596 on the afternoon of September 1, 2020。 The customer service said my bank card number was wrong so I should offer front and back photos of bank card and ID card. However, it wasn't changed after I had offered these photos. And I was told that I should pay 30% margin (￥43,078) for recertification. My fund and account were frozen by the platform separately for I didn't pay the margin.
