Kotak Mahindra Bank — Inward Foreign Remittance

My friend transferred fund from his Australia account to my Kotak bank savings account on 20/02/2023 for personal purpose. Bank hold my fund since then. I have visited my home branch three time and took my manager's number. I have submitted FATCA form as well as declaration for purpose. Mr. Bhavin Chauhan (Manjalpur branch Manager) gave him number and I send him transfer advice with transaction reference number and bank letter. He stopped talking my calls and replying my WhatsApp messages. Even he is not ready to share any resolution. As reputed bank in India, first time I had worst experience where I need to beg for my own money and they don't even care for it. Kotak Management should take some strick action against such employees just to make sure smooth experience for customers. As a manager he was doing his personal financial advisorary also. When I visited branch to follow up on my transaction, he took 30-35 minutes to explained different financial instruments and asked me to invest in this. He was not bother about my pain, he just want to sell his product and earn extra commission income. Kotak is paying him to address customers requests and to solve it but he is doing something else. Please help me to get my money back.
