Allschoolstuff.com — Have not delivered the order

Address:

Maharashtra

I had placed an order no. 341280 with allschoolstuff.com on 8th Aug. As per the website policy is to ship within a week's time. It is nearing a month now & so far no updates from them. Have tried calling their support number & also have written 7-8 mails without success. They dont pick up the calls & also dont respond back on the emails. The site should be blacklisted. I want my money refunded back. Kindly let me know how we can take legal action against them?
