Class Coin Didn't Unlock Class

So I saved 1 class coin and 1 XP coin specifically for the Dino Tamer.

So, I went on used my class coin clicked the Dino Tamer and it ate my class coin and didn't unlock the class . I re-logged a few times to see if it would unlock or my coin would come back but no luck.

So if i could get some help with this that would be great. Thanks.
