Help with lease Volvo

Well, I was talking about posts like this: Got charged $2000 for excessive wear and tear Volvo lease return

If you are only sent a bill but not charged yet, you can probably talk to them and get it reduced. Will they do the same and refund a part of your money if they’ve already deducted it from your MSDs? That will be bit of a challenge, no? I am not debating the benefit of paying the MSDs as it brings down the MF and thus the monthly lease amount.
