A professional complaint letter written to my insurance in Toronto, Ontario, Canada and insurance Superintendent stating my complaint and  the best resolution to both parties

I am looking for a professional complaint letter to be written to my insurance company and insurance regulator in Canada regarding customer service and compliance issues. My desired outcome from this complaint is return of premiums and/or compensation for any losses incurred due to the customer service issues. I am in need of someone with excellent writing communication skills and familiar with duty of care, fiduciary matters who can write an informative letter that outlines the complaint and requests a resolution that is satisfactory to both parties involved.
The person I'm looking for should also possess strong research skills in order to effectively communicate with both parties regarding the issue. If you believe you are the right person to provide this service, please don't hesitate to get in touch.
