Supervisor: I'm telling you, the promotion you claim you signed up for on the website does not exist. We never offered such a plan for 24 months.
Me: You definitely did offer it for 24 months, and I have a screen shot of it. I will send you the screen shot if you'd like.
Supervisor: I don't need to see the screen shot.
Me: So you believe me?
Supervisor: No, I don't need to see it because I know it doesn't exist. I am offering you 25% credit of the difference, and that's what I'm offering, which is generous because what you are claiming you got doesn't exist.
Me: If it doesn't exist, then surely there would be no problem accepting a screen shot from me proving otherwise, right?
Supervisor: I don't need to see it.
Me: You mean you are refusing to see it?
Supervisor: Yes. I have offered you 25% credit, you can take it or leave it.
Me: So you are cheating me out of 75% and don't want to see a screen shot that proves me right and you wrong?
Supervisor: I know I'm right and don't need to see any screen shot. You are not being cheated, you are getting 25% that you shouldn't rightfully get.
Guess the company.
