Thank you for reaching out.
You purchased a MIX. It is clearly stated in the title of the variety as well as the description of the item that it is a MIX.
I am not sure why there is any confusion. The label on the front of the seed pack states: This is a MIXED pack of seeds containing Black Beauty Eggplant, Petch Siam Eggplant and Turkish Orange Eggplant.
