Membership problem

I just bought a 1 month membership but then my game crashed and when I loaded it back up, a screen popped up saying "Purchases are pending. Please wait". Its been doing this for about an hour and I restarted my iPad several times but nothing is changing. So please fix this, I really want to be able to finish all the expansion packs before the month that I have is out.
