Rabbi Menachem Mendel Chitrik is in charge of the supervision and is always available to answer your questions in regards to kashrut at: [email protected] "

For more info from Rabbinate of turkey, an email is given - [email protected]

So it does seem to have the hechsher of OK and Rabbinate of Turkey.
I've edited my post above.
Hope this clarifies things.
