If you expect service from a company as a customer, you shouldn't be surprised they want to identify you. In fact they are probably doing so specifically because people were already social engineering them this way. Sure the stuff they are asking for is ridiculous, but that's because you are attempting to use non-standard channels of communication. You're getting mad at them for trying to meet you halfway. Pick up the phone. Send them an email. Use their contact form and have them contact you. This is all easily avoided. Personally I would never allow anything related to anyone's account to happen over Twitter DMs unless there was something like a system in place where you give them your Twitter handle during sign-up.
