Unable to withdraw funds

I want to withdraw money, but I am not allowed to do so because my registered bank account number is incorrect. How could it be wrong that I used a copied account? They also refused to let me withdraw the money on the grounds that I had not registered it with customer service for participating in the event. Another person kept persuading me to deposit more money, and said that if I didn’t use it, I would be compensated for the technical fees, which totaled more than 370,000.
