Where are my name change tokens? How will I apply them?

I bought a name change pack for three. I went through the checkout. I have not received anything in return other than the feeling of flushing 20 dollars away.

How do I access the name change pack? Specifically, how do I apply a name change to each of three characters? I can’t find any instructions on this topic other than to buy the name change service.

Start by looking at your account’s transaction history to be certain that the purchase completed without error.

Character service tokens will appear above the character list in the top right corner.
