Disclaimer: I don't fully understand what has happened so please excuse the bad explanation.
I had two apple ID accounts; X@yahoo.com & Y@me.com. And I have used the yahoo account now for 6 or so years now mainly for iTunes and more recently the Mac App Store. However when I got an iPhone I signed up to mobileme so I could have the Find My iPhone feature, but I continued to use my X@yahoo.com account to buy music and apps. However once iCloud came out I left the Y@me.com account and upgraded my X@yahoo.com account so I could start using the iCloud features.
I recently brought a MBA and noticed my contacts and other stuff was not syncing through my X@yahoo.com iCloud account. So I went into My Apple ID manager and didn't see anything strange. However when I looked at my iPhone and went to Settings>iCloud>Account I saw that my Apple ID was X@yahoo.com. BUT under advance it was "Mail - Y@me.com" which is something I hadn't set up. So I went to My Apple ID manager and tried to log into Y@me.com but I didn't know the password so I requested it to be reset by having an email sent to me.
Note I requested for my ME account password to be reset. Instead I got an email to my YAHOO account asking me to reset my password. So I went ahead and reset the password on my YAHOO account. I then tried logging into my ME account on the Manage My Apple ID website using the password I just reset for the YAHOO account. And it worked. I noticed that my YAHOO email address was the primary address for this account so I deleted it and changed it to another email Z.
In doing this, my YAHOO account somehow got deleted. I only realized this when I couldn't log into it anymore and resetting the password wasn't working. So out of curiosity I tried setting up a new apple ID with my X@yahoo.com address expecting it to say this email is already being used. But it didn't it created a brand new Apple ID.
This has now created two problems. The first I cannot access any of my old purchases I made on my X@yahoo.com account even though I am logged in as X@yahoo.com. (This extends to iTunes, iTunes Match and Mac App Store). Second I now have the old Y@me.com that needs to be connected to one of my emails which isn't a problem in itself but don't understand why a MobileME account needs to be linked to another email or have a different email as its primary email address. (I have other me addresses that don't have this problem.)
So I was hoping someone has experienced a similar issue to this and knows who I should call or speak to. I have called apple three times and they all have no clue, and since iCloud is a cross-platform issue I keep on getting "told off" because my iPhone is out of free technical support even though I just brought a MBA with Apple Care about three days ago.
Thanks for any help.
