Locked Out Of Blueyonder.co.uk Email Account

I have been unable to get into my VM email account for 5 days. I just keep getting the 'Forbidden' page. On day #2 I had a callback lasting about 40 minutes where I was repeatedly taken through the Account Settings/Identity & Security Settings/ Manage Your Products route to verify my GMail address but this accomplished nothing - kept going round in circles with the 'Try Again' message. On Day #3, I had a callback lasting about 20 minutes where I was taken through the Account Settings/Identity & Security Settings/ Virgin Media O2 ID route to verify my GMail address and change my account password but this accomplished nothing either - just get the 'Forbidden' message, as before.  The new password lets me get into my account to view bills but I still can't access my e-mail, so no progress.  Day #4 – no further callback from VM.  What will Day #5 bring? 

Is there anyone out there who can educate the VM call centre guys and provide a solution, please?
