Spice Jet Airlines — Not refunding my money

I have cancelled my itinerary (PNR: HF5RFB) from Chennai to Delhi (roundtrip) on 20th of Oct, 2015. But I haven't received the refund. I have called 8-10 times to Customer care of SpiceJet but still no progress has been made. They raised complaint with id CR/375801/2015 on 17th of Dec, 2015 and told me that their customer Relations team will get back to me at the earliest but no one contacted me by any means. Now its approximately 3 months but till date I haven't received my money back. Now their customer care numbers are not responding and when I mailed to spicejet at [protected]@spicejet.com on 28th of Dec, 2015, they replied that my account details have been moved to concerned department to process the refund and refund shall reflect in coming days but now its 10 days I haven't received my money. Then again I mailed them on 7th of Jan, 2016 they are asking me to have Your patience. I just want my money back because for me INR 8, 553 is very big amount. Please help me to get my money back.
