Hi Fong,
Our records indicate that you were sent an email apologizing for the error in sending you a the Size B chair and not the Size A chair as requested. We offered you a generous compensation to keep the incorrect size chair or the option of picking up the chair for full refund or exchange. In fact, a fedex pre-paid label was already sent to you.
Please contact our customer service department if you did not receive this information.
