Skoda India — Unethical behaviour, small rubber worn out with just 800Kms after service and they ask to replace the whole gear assembly

Address: Chennai

Hello,
I have Skoda rapid Ambition Plus 1.6 AT.
The car gear shifting was jammed in Parking Mode and went through a breakdown, I towed my car to service center and it was found a small rubber bush is worn out.
(breakdown happened 3Kms away from Skoda service center and no one from Skoda came to my aid, and i was stranded on the road from 11:30AM to 5:30PM)

Gear rod is the least used in an automatic car, and the gear rod facing issues in 40000Kms is not at all acceptable.

They have given me a quotation of 80, 000Rs to change the entire gear assembly saying the rubber is not available separately. And agreed this is a rare scenario and they didn't even care to coordinate to Skoda India regarding this scenario unless i raised a complaint on the dealer.
Car ran for just 800Kms since the last yearly service.
I have done all the yearly service in authorized Skoda service centers only. For such a premium brand car running just 800Kms against the promised 10000Kms is not acceptable.
My car is just ran 40000KMS in the last 6yrs, inspire of less usage i have given approval to change spares every time the service engineers approached me for spare replacement.
Worst behavior they asked if they can close the service saying customer is not able to bear the charges.(y cant they blame themselves that they can manufacture a rubber separately?)

I am not getting proper responses. Waiting for an appropriate response from your end.
It happened to me today, tomorrow it may happen to others also. Every time don't expect the customers to be understanding and pay the amount for your so claimed rare scenarios for which you don't have a rubber bush so u replace full assembly.
