Honda Cars India Ltd. — low quality part wrv navigation system

Address:

Samara honda Mayapuri, New Delhi, Delhi, 110046

Hi
I have purchased honda wrv from samara honda

After 1 st free service of my vehicle i found that navigation system is not working it was showing error of missing files.
But when i gone for 2nd free service at the work shop they told me your card is corrupted but i never took the card out of the car and they ask me to go to showroom.
When i reached the samaha honda mayapuri they told me this card is corrupted now you have to buy a new card worth rs 7000.
I asked the reason why card corrupted when it was never took out from vehicle.
I was shocked to hear that it might be done when your vehicle was at workshop.
If this is the quality of the product and service from the leading car selling brand in india honda car i m really disappointed.
Please tell what to do in this matter as customer care not supporting

Regards
