For the past several days I have been working on getting up enough gold to upgrade my royal hall from level 7 to 8. Cost is 4.4mil. I got up to 3.2mil. Then bought the remaining 1.2mil with gems. Cost was a little over 300 gems. Almost all I had. I upgraded and it started. Now today it is not upgrading. I don't have the gold and my gems are still gone. Who do I need to call to fix this?
