Tata Cliq — not get refund it has been over 40 days now

I had purchased two shoes one was bond street red tap, second was adidas running shoe worth rupees total rs[protected] and 2578 respectively) on 30th november 2018. Bond street shoe was too big and adidas one was of poor quality. Immediately i had returned these products but i got only one refund of rupees rs 1085 after 10 days and rs 2578 is still haven't received. It has been over 40 days still i haven't got that till date. They are just closing my several complaints by giving arm number and saying we have done transaction which is useless as i had discussed with my bank. Also i shared my bank statement with them. Its like you taken money from somebody and at the time of return you just through it some where and saying that i have done the transaction. Its not my headache if you transferred into wrong account or something else i need my money back.
