Dear (First Name) or Mr. /Ms. (Last Name)
I am writing this letter to inform you of my departure on (date), as I have decided to leave (the present place of residence/job, etc.).
I shall miss your company and the help and support you offered me in times of distress.
I will forward my contact details as soon as I settle in the new (place/job). However, my mobile phone number and email address continue to remain the same.
I look forward to keeping in touch.
