Nobroker — Unable to delete account

My account is used by another person hence I wanted to delete the account as NoBroker told me they can’t log me out of all devices that use my account. I dropped multiple mails to delete my account. They respond saying the account is deleted but when I open NoBroker app, it still shows me as logged in, it did not ask password or OTP, it is active and can be misused by people who have logged into my account previously to search houses. I’m unable to get my account deleted
