About time but excited they now allow you to have one login for savings and credit cards. The linking process was pretty seamless as well!

For some reason, I can't log in to my American Express savings account since they combined the logins for their credit cards and high-yield savings accounts last year. They were not able to get my accounts to sync properly, so they let me keep using the old HYSA password. But since then, they've taken away important tools from that old login, like the ability to move money between accounts. I've been talking to their login support team on a daily basis for more than two months. I've even talked to support managers who said they would fix the problem themselves, but I still don't have full control over my money. I tried to escalate the issue, but customer service on the phone told me they only have a few choices. AMEX's lack of growth and general lack of skill has been very frustrating. Do you have any ideas on how to take this further?
