Garena Free Fire Account Deducted 5000 Diamonds Unjustly

I've been playing Garena Free Fire for 4 years, and out of the blue, 5000 diamonds were deducted from my account. I have dedicated my time and energy. I've put in a lot of effort to earn the diamonds I've collected, but unfortunately, the game has become unplayable. It is not possible to claim the rewards for the event. Access to the profile is currently unavailable, and sending messages is not possible. I contacted customer support, and their response was, "You should not have made a deposit." I have a complaint to make.
