Double purchase by accident

Good day,

I was trying to set a droshipping system on test site and production website. I purchased by accident the licence on the test website. Can you please assist by cancelling the purchase for the test site, please.
The test website is teglux.fabe.ca and the product site is teglux.com
I am wondering how we can check get active the licence on the production site as it is currently working.
Many thanks

Nathalie
