No.
What is very important to know is that it's part of our code of ethics to work with our vendors in a win-win situation. When there is a bad situation, we contact people and we deal with it. We want to do the right thing.
For us there's no unilateral decision made for charging back. There is a conversation and then a cure, and a decision is made. It's in partnership. That's the way we work with our vendors.
