More than 2 weeks (without working cellphone) waiting to get repair on new, expensive, high-end cellphone, which is obviously defective! (Black screen of death) No estimated repair date provided, but cellphone had to be sent back to Samsung by UPS after 5 days in local, authorized repair shop! No loaner, no phone replacement, as with Apple. Other personal accounts have 2-step authentication which are tied to out of service cellphone, making access to all other accounts difficult, if not impossible. Emails & texts from Samsung give conflicting, confusing status. Customer service is non-existent---no one knows anything. They just apologize for your "experience."
