Property owing company is not returning the security refund

Hi, I rented a property in Gurgaon, which is a leased property owned by some Pvt Ltd company based out of Bangalore. They manage multiple such properties in India and also have website and App for same and is a legal registered entity. I vacated their property on 5 March and as per agreement, my 1 month notice period was supposed to end on 16 March and company policy states that I should get refund within 7 days of vacating the property. It's already more than 2 months now and every time I contacted them through customer care through phone and mail, I got assurance that they will do it soon. The local property manager kept telling me that I will get refund next week multiple times and we are already now in more than 2 months. They are saying they are unable to process refund due to lockdown, but it's a digital payment and I only got false assurances. What are my legal options, as I am exhausted contacting them multiple times (more than 30 times easily). I have all the necessary proofs.
