You're making my blood boil.
Calm down. Madam.
I'm about to explode! You'Ve made a mess of this matter.
I am very sorry to hear that you'Ve been having so many problems.
Sorry isn't good enough! What can you do to help me?
I understand why you're angry, Mrs. Wilson, and believe me, we are doing everything in our power to work this out.
Well, obviously, what you're doing is not good enough!
If you could just give us a few more days, we should be able to get this straightened out.
