To keep you all updated...
Applecare took note of my issue and then told me I needed to raise a case with iTunes support as AppleCare doesn't deal with account issues. So I did this via the Itunes support website as instructed and re-explained my issues to them.
iTunes support came back and said they would verify my account upon me completing a few security details which I did and they came back to say that my account was verified and should be working properly.
Upon testing with FaceTime I have the same problem still and upon logging into my AppleID account my email address is still unverified.
I responded to iTunes support who eventually came back and said I need to re-raise the issue with AppleCare. I've re-opened my AppleCare case and explained the problem again. I then got escalated to 2nd tier support at AppleCare who spent some time trying to fathom the problem despite not being able to deal with Account issues at AppleCare.
We went through various steps, one of which was to try my mobileme appleid (uses a completely different email address to the AppleID I want to use). This works on facetime without any issue, so that's all good.
Next we tried to reuse the AppleID I want to use, but reverted to the same error. Although interestingly now, a second error message box appears in it's own window (rather than within the FaceTime App) stating that my AppleID was already in use. This corresponds to some of the other experiences posted relating to this issue...
Next, we changed the AppleID & Primary Email address on my appleID account to an old hotmail account that I have, to see if the verification process worked. We did this successfully and I could sign into facetime using the AppleID. However, the AppleID and the primary email address were now my hotmail address not the address I wanted, so this wasn't the solution, but proves that my AppleID account is working in every other aspect for FaceTime purposes.
Next we tried to revert the AppleID and primary email address back to my personal email address, during this process no response is received on the web page, the progress bar takes a while to complete, but no message to say that my account details have changed etc and the account remains un-altered. So clearly there is some issue with the AppleID I want to use.
So currently, my AppleID is linked to an old hotmail account that I no longer use and all my iTunes credentials / iPhone etc is complaining that my AppleID is invalid (because it's been changed). iTunes seems to be easy enough to resolve by logging out and back in again with the hotmail address, but I cant update apps on my phone at the moment as it keeps prompting for my AppleID password for the old AppleID and I can't seem to change it (but that's another story/___sbsstatic___/migration-images/migration-img-not-avail.png).
We then thought we'd try and use the appleid website to see if it could identify an account using my AppleID (eg using the Forgot your AppleID link). This couldn't find a corresponding match for my AppleID as you might expect since we'd just replaced it with a different one. So in theory, my old AppleID should be available to revert back onto my account. Yet it won't work.
The AppleCard 2nd line support then said they would have to escalate it to iTunes support on my behalf. Yesterday I received an email to say that I can't change my AppleID to my old AppleID because it is already in use/___sbsstatic___/migration-images/migration-img-not-avail.png/___sbsstatic__ _/migration-images/migration-img-not-avail.png/___sbsstatic___/migration-images/ migration-img-not-avail.png So clearly they haven't bothered to read the AppleCare of iTunes Support case history and I have had to re-explain the issue for a 4th time
So, now I'm waiting for some further feedback from Apple on this (from iTunes support) and in the mean time, no app updates etc on my phones for me 😟
Will post back here once we get any further.
Cheers
