你可以先心平气和的跟Customer Service的人讲你的理由,如果他们不接受的话,你可以记下他们的名字,然后跟他们讲:I still wish I could resolve this issue with you, because I don't believe this charge has any ground. If however you and your manager can not help me, I will have to turn to your public relations department and CEO office or even further for more help. I hope that I don't need to go that far because the conversation between you and me today will be mentioned in the communications and I think it may not be fair to you for your name to be mentioned there. I believe it would be mutually beneficial for you and me to resolve this here. Please reconsider and let me know your final thought.
如果这样他们还拒绝你的要求,那就进行下一步了。
