On Facebook:

Facebook processes payments made on its platform. If you purchased gold on Facebook and it did not show up in your War Commander account, you will need to contact Facebook support. KIXEYE has no way to access or verify purchases made on Facebook. You will need to dispute the purchase with Facebook.

Start by going to Facebook and clicking the gear icon in the top right-hand corner, then selecting Account Settings > Payments.

When a specific purchase is selected, you will be shown the description of that purchase. A dispute can be filed from this page. When contacting Facebook, we suggest you use the term "Credits" and avoid using the word "Gold," as they may believe you're referring to game content and advise you to contact us instead.
