Toyota — non delivery of navigation system

Dear sir,
I made a purchase of two toyota fortuners both from kanpur showroom but they delievered one vehicle from kanpur showroom and other one from lucknow and they didnt provide me navigation chip from lucknow showroom and mr. Ramakant convinced me to provide that from kanpur showroom.
Having believed them i returned back as they said will deliver navigation on first service. Since then its being 7-8 months and yet i have not recieved the device.
Its very frustrating that your valuable customers have to face problems even on purchasing vehicles of nearly 1 cr.
I expect you will work on complaint as soon as possible.
Details are as under
