Bata India Limited - Delay in refund

So the thing is they sent me a refund link on **nd december. It had two options UPI and Bank Account. I selected bank account and after filling bank details a new page opened up in which i was supposed to enter the OTP. But OTP didnt came on my registered mobile no. Or email id because they has issued refund link against some unknown phone no. Or email which starts with ** and ends with ** and email starts with asw. This is not my registered no. Or email id. They didnt ask me before sendind refund link. They didnt very my no. And email id. So the unknown person who received the link enetered the details in upi and received refund. Now the co. Is saying that refund is successful from our end. They are just fooling me around. Its been ** days since i applied for refund. They dont reply to my messages. Customer support is worst. When asked to talk to senior they say they are busy. I am a CA student and i have to study for my upcoming. Because of their stupidity and all this hassle i am not able to focus on my studies. I am being tortured mentally by their team. Its not a small amount. It really matters for me. They are not sending me new refund link. They just say we are checking with our team and we will solve it within *-* days. And now just like that ** days have already passed. I request the authority to look into my concern and solve it within *-* days. I cant wait more. I am not able to focus on my studies. Its really affecting me mentally. I have all the proofs, my bank statement etc. I didnt receive any refund. And without solving my issue they marked my ticket as resolved and closed it. They just keep making fake promises to solve it within *-* days. Please help me. Its my very humble request to the concerned person. I have all the proofs of bank statement. No refund has been provided to me.
