T-Mobile AAA Year on Us Promotion Code: Not Working for Me

I've had some similar issues as well.  I attempted to sign up, but the webpage said I already had a membership, and to log in, with that.  I tried…..no membership found.  I went back, and re-entered all my information.  'Member information already exists', so I attempted to re-set the password.  No membership found.  (I HAD a membership over a year ago, that expired, when I relocated to a different state, but now, it cannot be found, or used.) I called AAA customer service, and was told this offer only applies to 'brand new members who have never have been a AAA member before', (even though the T-Mobile offer clearly shows available for new and existing AAA members…)  😬
