My iPhone Garageband files that I stored in iCloud have vanished. Has this happened to anyone else?

I have an iPhone 5c. Since I upgraded to iOS 8, I haven't been able to find the Garageband files I uploaded to iCloud. This was the case before and after I converted to iCloud Drive. According to Apple's info on iCloud Drive, I should have no problem accessing the files if I'm using an iOS 8 device (I'm not trying to access them with my computer, just my iPhone). I've seen other people posting about problems with Garageband files in the cloud, but most of them can actually see the files in the cloud and are having problems with functionality. I can't find any trace of my song. I'm certain that I uploaded it, I just don't know where it is now. I deleted it from my device once to free up space, but again, I deleted it from my device, NOT the iCloud. Just wondering if anyone else is having problems with files being deleted from iCloud, and if you have come across a solution.

Tip, never store your important files in the cloud. It's best to save it into a computer or safe hard drive where you know it will be safe.
