My Apex coins were deducted 11500 without any violations

My Apex account was deducted 11500 gold coins, but when I contacted EA customer service, the response I received was that my EA account did not have any illegal recharge or refund operations. At the same time, I consulted the Steam customer service associated with my EA account and received the same response. So I want to ask why my 11500 gold coins were deducted? I asked EA customer service, and they said they couldn't give me an answer, they just told me to check my account and there was no violation of refund. So I request to restore my Apex coins and refund the deducted 11500 coins.
