Purchased a flagship Samsung phone. My account, which i haven't used for 4 years, still has my old phone number. When I attempt to change to my current number using their website, it sends a 6 digit code to mt emailWhen I pick up that code and attempt to return to the email demanding that code, it starts all over from tgr beginning. Unable to use ggeue system fir such a simple update of a phone number. When I called customer service, they are unable to help, but offered to walkme though the process which again does not work. Samsung makes nice products but their " customer service " is useless. BEWARE!!!
