Few months ago, I couldn't login to my account after failing to answer some questions. Then, my entire Amazon account was suspended because i couldn't remember the mailing address in file in order to reactivate my account. At the end, they asked me to recreate a new account and all my digital purchases are gone forever. Their customer support staff were also very rude and unfriendly when i called them up. Why can't just they send me a password reset thru email like most companies do?
