VLCC — need my money refund. total useless, the poorest customer support

Took weight loss session few years back and couldn’t continue since i got pregnant immediately so i started calling them for the solution later and no one bothered to help me out. Sent n number of mails and calls to customer service people but no one replies me properly everytime they say u will receive a call shortly from the branch and nothing happened till now. And everytime i call this stupid customer service and i have to give the complete details again and again, they don’t even track anything from the mobile number. Such a useless system. Now it’s hightime can’t wait anymore i need my money back. I paid 20k it’s a very huge amount for me. Anyone can help me out on this?
