Where is Odus' Special Costume reward?

I had a notification just today to play all six levels to get a special Odus costume but I did not take a snapshot of the pop-up unfortunately. I completed all six levels and was looking forward to receiving the prize but it did not show up. I have screenshots of the prizes I received for your perusal and reference. There was nothing at the end of the completion of the levels to say that the player has to play and finish another 10 or 15 levels to be awarded. I am very disappointed. Please advise.

Thank you.
