It is really sad to hear about your bad experience @lika however, I must say that I am not at all shocked by this problem of yours. It is appalling to see how VAG takes Indian customers for a ride by giving us their magnificent piece of "GERMAN ENGINEERING"
.As there is no point in ranting about the VAG's state of affairs in India I will go back to the topic.
You are from Delhi therefore can you please tell in which esteemed Volkswagen dealer your car is resting? (I hope it is not Volkswagen Delhi South - Lots of horror stories from there
Can you please specify whether they are changing the whole clutch assembly (Master/ slave cylinders)?
Also, I would like to suggest you to visit Volkswagen Noida dealer they seem to be the most honorable among thieves.
