Simply call, let them know you're having a hard time making a multi-city booking through the website, give them the flights you want and mention the 10% off promo code. It has worked every time I've tried, and they waive the phone booking fee too.
As for the log in issue online, I've found that if you log in when prompted, and then hit 'back' on your browser and go through again it works just fine. Weird, but it works.
