Just got a call back today. She asked where I found the promotion, and then she said she'd go look it up and call back. Couple mins later, she actually did call back and read off the details of the promotion, and asked for the coupon code again since she didn't see it on the account. I gave it to her, and she said someone else would apply it to the account, but if there were any more problems, that I should give her a call back. It was actually pretty easy. I mean, of course it would have been easier if the system actually took the code in the first place, but technology sometimes doesn't work and the way it was handled once I was talking to supervisors was very efficient.
