Tata Motors — Delay in vehicle delivery

I am Jayakumar from Kerala and my phone number is [protected]. I booked for nexon EV xzplus dark edition on 10/08/2021 in DERIK MOTORS Trivandrum in the name of SMITHA. At the time of booking they offered vehicle delivery within 45 to 60 days. After 45 days I contacted these guys several times and each time they said to wait for one more week. On 26/10/21 they telephoned to me and said vehicle reached and requested to make payment so they can register in the next day itself and thus I paid total seventeen lakhs and 10 thousand rupees, but after that they are not responding to my call.Is Derik motors is your authorised dealer and if so please do the needful to deliver the vehicle at the earliest.
