American Express Are Dumb
I'm pissed off and I'm hoping that ranting here will help. When I rant like this I cling to the extremely remote hope that someone in charge will someday read this.
It could happen!
My problem today is that American Express' web site was designed and/or implemented by dickheads. Here's one example that keeps trippng me up - you can enter a password of unlimited length on the front page, but if you sign into your account on the small business page you are only allowed 8 characters in your password.
My strong password* is 10 characters.
Now, all would be fine if they told me that initially. But instead they chopped off the last 2 characters when I registered, then did the same when I signed in. So for the first year everything worked even though I didn't realize I had an 8 character password.
But if I try and login on the front page it always fails, because it allows me to enter 10 characters. And then my account gets blocked and I have to call them and get it unblocked again. This happens regularly now because I've had my password reset so many times that I've lost track of how many characters I can use on which page.
I know it's not just me; my wife has the same issues trying to login. Actually, that's a big comfort. 
* Yes, I'm sorry, I use the same 'strong' password on all banking sites. Life is too short.
