When I have a problem with a company, I normally call in a complain to a manager. Try calling in and explaining your story, then ask for a manager and re-explain your story. They got to the position of manager by being qualified and pleasing the customers. I'm sure they'll use their mojo to give you that discount.
I haven't done much lately, but a week ago I called microsoft and got Skyrim for free. (Not dropping my method publicly)
TL;DR:
Call company, explain problem, get discount (hopefully?
)
