Gleam Technologies - Secirity Deposit not refunded

In ****, ₹**** was paid as security deposit to register for part-time at Glram Techonologies. They assured to give it back within a year. Since then I have contacted their customer service through phone calls and mail. They have never responded to my mails and on calls they made up excuses like asking me to talk to their seniors and never connected me throughm This has been going on for more than a year. I demand the refund of the deposit I made and also mental harrasment that I have been facing for the past year.
