Sometimes you don’t need a budget
Most of the time, people don't want a refund or a bonus. What they really want is for you to hear them and to do the right thing. What if every manager and every customer contact in your organization bought into that?
Here are some things you can do that don't cost any money (but they certainly require effort):
Treat your employees with care and respect
Be consistent in your actions
Keep your promises
Grant others their dignity
Give credit
Take responsibility
When wrong, offer a heartfelt apology
Don't be a jerk
Take the time to actually listen to people
Volunteer to handle the issue
Care
