Gold bars

Hi,

Somehow my account across my iPad and iPhone got the synchronisation mixed up and when I was finally able to get into the account through my iPhone the gold bars all reset to zero. My boosters and progress saved but all the gold bars are gone. How do I get the gold bars back? I had over 300. I have attached screenshots of my screen which I luckily took before it reset to zero. I think the problem was because it somehow started saving the account through my Apple ID and wasn’t doing it through my Facebook so my avatar wasn’t coming up but my progress and boosters etc was all there although I couldn’t participate in any events. It was like I was playing offline. So I deleted the app on my iPad and closed down my iPhone and when I reopened it, I was finally able to login into Facebook （previously it couldn’t and said there was a connection error). But all the gold bars was zero.
