Zoom Car — harassment & service level mis-commitment

1. I have taken zap service since jun'20.
2. From the very beginning, the delivered car was faulty and i escalated the same from the very first day in different ways. Through call, mail, service agent etc.
3. However no proper action has been taken since last more than a month. There are numerous issues in the car. But replacement of the same has been happening since last more than a month.
4. I am now frustrated and decided to close my zap subscription. I will arrange the car from another operator.
5. Since you have not maintained your written commitment as per service level agreement, i am also not bound to do so. Please guide me how to submit the car.
6. For your reference, i am quoting the ticket numbers that i previously raised 468938, 469445, 467247.
