Terrible
JD.com (JOY BUY) forced me to pay an extra $35 for the same product, because it was not sent for some unexplained reason (after I had to follow up after 3 weeks of ordering). From China to HK, should not take that long. They did not answer reason for delay and refunded the $25. Due to the unreasonable delay, I had to pay a higher price to buy the same product, (which I originally bought for $25 originally). That was on 16 July and still waiting for reason for delay some kind of compensation.
