I have to agree, I've also suffered account problems. I was locked out from an email address I used for 20 years. It refuses to take my password which is still valid. I've changed phone number since 20 years ago so can't use that and the security questions were nonsense as I was a teenager. Originally my account never had phone number, they insisted I add it when they integrated my Skype account perhaps. So I didn't expect access to that phone number to be a strong ongoing requirement.
