Why is my bank charging me a service fee?

Excuse me, could you please explain why my bank is imposing a service fee on me? I have always been diligent in managing my finances and ensuring that my account remains in good standing. I understand that banks often charge fees for certain services, but I'm unsure of the reason behind this particular charge. Could you provide some clarity on the matter and perhaps suggest ways to avoid such fees in the future? Thank you for your time and assistance.
