One Bag Missing

My flight was from Dhaka to Istanbul flight number  TK 0713  on 20 June 06:10, and my second flight was from Istanbul to Houston flight number TK 0033 21 June 13:05. When I arrived  to Houston, I was getting all my belongings, but  in my luggage there was one bag missing. I did not found one bag. I did email to the luggage department, they gave me this website to complaint about my missing bag. Kindly give me a call or email me regarding this matter as early as possible.  Thank You.
