I understand, but
Shows you heard their answer, then repeats what you need. Calm and hard to argue with.
Examples
I understand, but I'd still like you to look at the full charge.
I understand, but the money was only late because of the bank holiday.
In a conversation
A: I'm sorry, the fee is applied automatically.
B: I understand, but I'd still like you to review it. It was one night.
Common mistake
Not: I demand that you cancel this fee.
Say: I understand, but I'd still like the fee cancelled.
"Demand" sounds like a threat in everyday English. Calm repeating gets you further.
