Waste of time

It was my third order, but it wasn't so lucky as previous. I have paid for the order and got an email with warning that my order processing time increased due to high amount of requests. After almost 3 weeks I wrote an email with question about my order status, but didn't get any answers. Passed one more week and I received message from Paypal that I will be charged back, with no explanations at all from this shop. It will take up to month to get my money back, so in summary - it's just waste of time for me.
