Maruti Suzuki - vehicle delivery delay

I hope this letter finds you well. I am writing to express my dissatisfaction with the failure to deliver the vehicle as per our agreed-upon terms. The details of the transaction are as follows:

Transaction/Order Number: [Insert relevant number]
Vehicle Details: [Make, Model, Year, VIN, etc.]
Date of Purchase/Order: [Insert date]
Dealer details: Bimal Auto agency, Sy nos **, Bimal Auto Agency, No. *** & ***, to, ** of, Amarjyothi HBCS Layout, Domlur Village, Domlur, Bengaluru, Karnataka ******

Despite the agreed-upon delivery date, I have yet to receive the vehicle, and the delay is causing considerable inconvenience. I have made attempts to contact dealer Bimal auto agency [phone/email/other communication channels], but unfortunately, I have not received a satisfactory response or an estimated delivery date. I kindly request your immediate attention to this matter and a timely resolution.
