Swiggy — about misuse of my mail id

My mail id [protected]@gmail.com is active for more than 14 years. Now it is used by another person from kochi, kerala to buy food through swiggy.
Because of this i could not log in swiggy with my mail id. Whenever the other person buy some food items, swiggy forward the details to my mail id.

I have complained to swiggy once about this by mentioning all the details. I attached a bill too received from swiggy. But they have taken no action.
I am attaching a bill recently received from swiggy for the food bought by the person in my mail id and who is not known to me.
