The sweater is ruined.
We will refund the cost of the laundry.
You may buy a new sweater and give us the receipt.

I'm terribly sorry for the inconvenience.
The collar is a bit scorched.
It's a pity that the sweater you sent back shrank badly.
I'm here to express my apologies to you on behalf of our housekeeping. We'll pay you an indemnity.
The indemnity shall not exceed ten times the laundry.
Also we'll refund the rate of laundry.
You can have another choice.
