The products are great and worth the price. But i dont know why, they never send the complete products as written in the invoice. I always got missing items not one or two pieces, but a lot! But luckily the customer service are very helpful and willing to refund all the money. Maybe you should fix your work in packing part and give the customer updated invoice so we can know which one is out of stock and which one available. And also make the system for credit balance automatically back to our credit balance without us asking you.
