I bought two pairs of shoes and returned one pair. They said I would receive an email regarding the refund within 14 business days when they received it. It's been 15 days today, but I haven't received any refund-related email, nor have I seen any refund in my bank account. I emailed the customer service about it, but haven't got any response. How can they run a business like this? I won't buy shoes from here again.
