They charge you first and then don't commit on their delivery. And don't respond to your emails.
Before placing the order they committed that the books will be delivered within 3-6 day. After 6 days when asked they said we take 5-10 days and gave me a date which more than 10 days ahead. I asked them to refund my money and cancel my order. But now they don't seem to respond. This is extremely rude.
