Volkswagen — Volkswagen Quality concerns

Address:

Gurgaon, Haryana

Background
I had purchased Volkswagen Vento Highline in the month of SEP 2010 thinking that I was buying one of the best quality product from Germany on the contrary I have been constantly facing quality issues in the vehicle .
Alloys
In last 2 years 11 months all the 4 alloys of the car got bent.
First 3 alloys got bent in the month of April 2012 and fourth one in Sep 2013
The cost of one alloy is INR 20 - 22 thousand rupees and it is not possible for a customer to pay from his pocket. In April 2012 I had to literally fight with the insurance company and after sales team of VW .It was only after a wait period of 40 days insurance company replace two alloys and fixed one of them.
I had raised the above concern to VW customer care team about the quality of alloys and their standard reply was it is because of the external damage.
Now, In Sep 2013 another alloy (fourth one) got bend and I have given this vehicle in Gurgaon workshop
It is understood that one of the alloy can get bent because of external damage however how it is possible that all four alloys got bent in just 3 years
Dead AXLE
Recently, In Sept 2013 my car was bumped by a bull and I have given my vehicle for denting and painting job . The information I got from the workshop people that now DEAD AXLE of the vehicle is bent and it is not covered under warranty . This cost of this part is 1 lakh rupees for my Vehicle which was launched in 2010 whereas I have also leant that Vehicle which were launched in 2012 have a cost of only 15,000 for the same part
I do not understand
- Why there is huge difference in the cost for same spare part ?
- When VW is providing such expensive spare parts in my vehicle how is the quality justified under above circumstances?
Alloys - Rs 22,000
AXLE - Rs 1,00,000
- Why Dead Axle and Alloys are not covered under warranty ?

I am not in a condition to afford replacement of such expensive parts
Requesting you to take this matter with Volkswagen after sales team to get justice for replacement of the complete Vehicle or aleast replacement of these parts
