During my trade on December 12th, it said my margin was insufficient. I tried to deposit but failed many times. I asked the customer service, who told me switch another browser or bank.

During my trade on December 18th, it said my margin was insufficient. I tried to deposit but failed many times. I asked the customer service, who told me switch another browser or bank. I tried but failed again. The only thing I could do was watching my position gets liquidated. I asked the customer service, who said why I had to use UnionPay when they have dozens of channels.
