Zoomcar — My car is not starting after the iot device fitted in it

This is the worst company I have come across. I unfortunately signed up with zoom car to list my carin August till date the the device still exists in my car which is draining my battery life and my car is not starting. I called the customer care hundred times and I have till date not received any resolution from your side. Annoyed and dissatisfied with the way this company functions. I am going to file a case against you. Kindly share your legal department details or email id where I send you a notice. Reply to this urgently
