Shop CJ Network — not get refund by shopcj even after 3.5 month

I have ordered carpet from shopcj on 18 dec 2017. But delay and wrong courier details i did not get the product. After my call on 5jan 18, they reordered in background. I asked them to cancel order and refund. But did not received refund. But support executives are talking very wrongly and don't provide the correct information. They say me that i will get in next 3-5 working days. But now it is completed 3month completed but did not get refund. Now i am preparing legal against this company.
Advising everyone not to order anything.
Thanks,
Jitendra pandey
