ITunes plus loop. Upgrade song, download song, iTunes finds same song...

Question

I seem to be stuck in an endless iTunes plus upgrade loop. iTunes Plus finds a song to upgrade I pay the $.30 I download the song. When I visit iTunes it finds the same song. To try and get out of the loop I buy the same song again. When I try to download it, it gives me an error message. I go to my account and hit the problem button. I receive and e-mail saying problem has been fixed. I go back to iTunes Plus and the same song is there, I buy it again (even though I've already bought it and successfully downloaded it), the loop begins again. I actually have 2 accounts and it's doing this on both of them. The second was created when I couldn't remember my user name. Different account, different song, same loop. I think there should be a lot of new stuff available to upgrade but I'm stuck in this loop and so I'm afraid I'll never see it.
Apple support gives me 3 or 4 answers to non-related questions and the only input I am asked for is to rate how well thayve answered my question. Well they haven't and I don't want to waste (even more) time on something that is not going to address this issue.
Is anyone else experiencing a loop like this?

Answer 1

I've visited the online support and was presented with a few itunes problems none of which are even close to my issue. I chose one and received an e-mail requesting screenshots of the problem. I sent in the screen shots and received another e-mail stating this is a technical issue and not a billing issue and given a phone number to call. I've called the phone number and was told by the tech support that this was not a hardware issue, that they could recommend I reinstall iTunes and authorize and de-authorize my computer.
While I was on the phone with tech support I visited iTunes and noticed the offending iTunes plus upgrade had disappeared as well as the additional songs recommended to me as being available to upgrade. I searched out the album and was told that I had already purchased this and was I sure I wanted to purchase it again? Actually I had purchased the DRM version and wanted to upgrade to the non-DRM version but this was not an option available to me. I chose not to purchase it again. As I told the tech support guy, if I'm going to purchase an item twice then I'm going to purchase it elsewhere so that I can get a better quality file ie FLAC WAV or at least 320 kbps. Unfortunately I've already spent a bunch of money repurchasing items that I'd purchased at iTunes before realizing that they would not play on other software on my computer...
I de-authorized and reauthorized both accounts, no difference. I'm going to try reinstalling iTunes and if that doesn't work I'm just going to give up on it. This is way too much trouble to replace a 128 kbps file with a 256 kbps file. I would have to say that I love Apple they make some great products but as is the case with most companies nowadays their customer support is sorely lacking. I'm exiting the infinite loop and going to continue purchasing my music online from other companies that do a better job and offer a better product...
