I have the same issue, it's never been available. There won't be much that can be done without sending a support ticket in. Support was very helpful getting another quest completed, we had to go back and forth for a few weeks to get it done. When I submitted the ticket for that quest, support asked me to do a few things, I did what was asked, replied and this went on until a fix was finally figured out. It's worth doing, just have patience and keep checking your ticket. BTW, if it says "closed", that just means support replied, it doesn't mean you're done, just reply back and it re-opens it. Hope this helps.
