Minecraft Realms iPhone issue

I purchased Mc Realms so i could use the maps on the marketplace on my ipad and iphone. I was charged and it says i have realms, but it can't finish up apparently and i cant access any of the maps even though i was charged and paid the 8 bucks to play the maps. It keeps saying it'll set up realms later but every time i check later it doesn't. It's already been a week or two now and i still can't get in and i don't want my money wasted.
