Chinese sellers are fucking shit. No matter what site you use, they all do the same thing. I guess I'm kind of used to it now.
So what is it they do? They will respond to an order quickly. They will claim they are processing the order, and then they will claim they are shipping the order. You will get a confirmation that the order has been shipped. Then like a week later you'll notice the shipping has been cancelled or the order is delayed in some way. And then you can be waiting for weeks for them to actually do something. lol
They give you the worst service you can imagine, and it's all intentional. It's simply how they operate. They give you the impression the order has been shipped so that you don't cancel and order somewhere else. Then they say it has been cancelled or delayed weeks later. Wait a minute, I thought you had already shipped it?
It gives you the impression that you're being scammed. When that first happened to me, I thought I was being scammed. Eventually though, you get the product you ordered. You get used to it. It has happened to me every single time. Every Chinese seller does it. lol
