Swiggy — Refund amount not received

Swiggy has to refund me 372 rs. which they haven't done so. I claim they have refunded. Even after so many conversations and mailing them my bank statement they still say me to contact the bank even if it's their problem to solve. Still, I contacted the bank and the bank also said that the money hasn't been credited. So now swiggy is also not cooperating nor returning my money. I have no option but to raise a complaint. I need my money back as soon as possible.
