Audio not included in the video Template - Do we have to pay twice ?!?

Dear. I am not a professional. I paid for 1 month subscription substantially to download 1 video template (Thriller Opener Video Template) and to use it for fun with friends and family for Christmas.

I was surprised to realize that the video doesn’t include that audio

SHOULD I PAY TWICE ?!?

NOWHERE I HAVE WRITTEN THAT THE AUDIO IS NOT INCLUDED.
SHOULD I HAVE TO BUY IT IN THA AUDIO JUNGLE ?!?

I REALLY DON’T LIKE THIS COMMERCIAL APPROACH THAT IS NOT CLEAR AND TRASPARENT

WHAT DO YOU SUGGEST TO ME ?

THANKS

GIOVANNI
