Hyundai Motor India — Not delivered booked creta

I booked a creta car 1.5 crdi MT E on September 1, 2020 via himgiri Hyundai, jhilmil, delhi. More than 4 months have passed and my car is not delivered. They even didn't tell me the tentative date. I talked to crm Hema, mrs shilpi and Rashid but they just fool me and do not answer. Plz tell why I should not sue them for misinforming me and causing so much mental trauma and waste of my time. Order no 1223/2021/NB602 booked by name of anurag singhal phone no.[protected], email [protected]@rediffmail.com
