Constant Error Messages with Purchasing & Downloading on iTunes with iOS 7

Question

This is getting ridiculous. Ever since I downloaded iOS 7 when it first came out, I've had difficulties making purchases and downloading content wirelessly using iTunes on my iPhone 4S and iPad 2. Every time I tap "Buy" I get a message that says the "Content Cannot Be Purchased At This Time." I then have to close iTunes completely (double-tapping the HOME button and swiping up on the iTunes window), then re-launch iTunes, find the content again and re-hit Buy and then I finally get the button to Download Now and Download Later. Choosing Download Now, I get another error message saying "Content Cannot Be Downloaded At This Time," and I have to do the whole shut down/re-start process all over again to finally have the download start. This happens when I attempt purchases using 3G and on wifi (and I've tried several different wifi networks and I get this error all the time).
I never used ot have problems like this on my 4S or iPad 2 before iOS 7. I tried restoring to factory settings and then moving all the content manually back from the iCloud and my computer and I still get the error. I tried signing out of my AppleID and logging back in, still get the error. I downloaded the latest iOS 7 software (currently running 7.0.4) and I STILL GET THE BLOODY ERROR. Calling AppleCare, they have no freaking clue why I'm getting this error and neither do the Genius Bar people.
There doesn't seem to be anybody else (that I can find online) who has the same problem. But there also doesn't seem to be anybody at Apple looking in to this which is incredibly frusturating. I've been submitting Bug Reports to the Apple Feedback pages for over a year now and still no acknowledgment from Apple. I also have been having the issue where my iPhone/iPad iCal apps keep reversing my Alert preferences (which I've noticed people complaining about for over 3 years with no solution from Apple).
This is getting out of hand. I've been a loyal Apple customer for the better part of a decade. I switched to Apple over PC because of their committment to excellence and relatively lack of bugs in their software. But lately, Apple's quality has suffered tremendously. When there are iOS software glitches that continue after 3 major updates (and several minor ones), clearly Apple engineers don't give a crap about their customers or the user experience. If these issues aren't addressed, I'm seriously going to take my business elsewhere. There is simply no excuse.

You won't see Viber data in www.icloud.com.  App data (e.g. Viber) is included in an iCloud backup or iTunes backup which includes other information.  Kindly see this support article for more information - http://support.apple.com/kb/HT1766, https://support.apple.com/kb/ht4946 and http://support.apple.com/kb/PH12519.
