Dear Seller, I called the Discount Loft at Harbourfront today to request for an exchange as advised by you yesterday afternoon. However, I was told by the lady who answered the phone that I have to request through Qoo10, no physical exchange is allowed. Is this correct? I saw that others can exchange directly at the store. So I'm puzzled. My item is 14140/gybl size us8, received yesterday. It's too big for me. I need us7. Please address this. Thanks.
