回複：被該店的經理侮辱了-希望大家能給我些建議

Where is the receipt?
Return price is based on the receipt not based on the current price. If you present the receipt, then it should be a piece of cake. However, retail business provides jobs to people below average intelligent. I am not surprised that they are stupid.

You have two advanced degrees do not necessary mean you can speak English. Those just means you stayed in school long enough.

No need to go to lawyer. You just go to the company's website and find their customer service number. Then call the customer service and they will take care of it.
