I recently dined at a restaurant and had a less than positive experience.
I sent the relevant restaurant some feedback. The restaurant very kindly offered to waive the cost of lunch and refund me the amount spent.
As I was not comfortable accepting the refund for various reasons, I requested that the refund be donated to charity.
I think it is more important for the service provider to learn from the incident and put in place a system to better manage its customers, which the restaurant has assured that it will do.
Please consider the environment - do you really need to print this?
