I don't think I was well informed by the customer service that I need to retain the balikbanyan box receipt in order to claim back the $10 deposit. Hence, I didn't keep the receipt. I only know that once I send the box out, I will get back the refund. The new box is already evident that I have paid for the box. So why do I still need the receipt. Why can't just make me sign something to acknowledge that I have taken back the $10 deposit.
