Mr. Manny Frost
Dear Mr. James Seth,
This is John Doe and I have worked for 4 years with the Technical department of DataCom Solutions as a senior technician for the period of August 23, 2005 until the effectively of my resignation which was August 13, 2010. I was replaced by Mr. Harry Smith on August 14, 2010 , a day after the effectively of my resignation from my post.
Despite the fact that I have completed everything that needs and are expected to be settled from my end until now, I still do not have my experience certificate and my relieving letter which will be important for the company that I will be working with. One month has already passed since I resigned but my experience letter is still pending. I am positive that you will help me in this matter and I wish you can reply the fastest that you can.
Thank you and Regards,
