Vahathi Motors Driving School — Refund amount not getting from Vahati motor driving school

Hi, I have paid for Vahati Motor driving school Kasanavahalli branch on July 12th to take car driving classes. I took 3 classes from 21st July and then I became ill and asked to continue after 5 days. But they were not able to schedule any classes on time and so I asked to refund the amount and contacted main branch in Bellandur. They agreed for that but after multiple follow-ups they are not refunding the amount. It's been two months i am asking for refund but no result.
