Purchased Liscense to 23 Assets No Longer Available

I have 23 assets like this that are unavailable. I have never used them. I asked chat for credit for these assets and they just left me sitting for 20 minutes with no reply. How can I get my credits back? This is ~$50 worth of product and two months of planning down the drain. I don't see any point in continuing this service if I cannot use the assets.
