How do I apply my purchase of a single call?

Once you purchase your single call, you just need to pick which call scenario you would like to unlock.

You will need to head to the Calls page, and choose one of the premium calls. Select personalize, and go through the steps.

Once you have completed the call form and select create, this will apply your single call purchase to this scenario and you will be able to place the call from My Creations.
