Swiggy — Delete order history and account request

Hi, I have mailed many times to swiggy to please delete my account. But he is not listening. I told him to please delete my order history and delete my account of registered mobile no([protected]) and mail-id [protected]@gmail.com but they continuously saying one thing in mail that it's not possible.
What is wrong with swiggy, please help me to do this needful
Thank you
