Skoda India — skoda car headlamp issue

Address: A/P Kundal, Tal.- Palus, Dist.- Sangli, Sangli, Maharashtra, 416309

Sir,
My name is ranjeet lad, and i have purchase the skoda octavia style plus from auto bahn. From last 15 day my left head lamp led light has become fade, so i have send the car to auto bahn itself to replace in warranty as the car is under warranty. 12/11/19 i have left the car at showroom and 13/11/19 morning they calls up and tell that it cant be/ /covered under warranty as the lamp inner part corner is broken, where bolt is fitted. And last time one year back that headlamp was open by auto bahn sewri workshop only to change the bumper and fluid washer tank. When skoda customer care took the workshop in conference the manager said that it is one year back issue how can we check and it can be broken bcoz of jerk or overtighting also, now skoda cant absorb jerk, then whose fault it is or the other over tight it was done at workshop only then whos fault it is???
Even today i got customer care call she said that the part was removed one year back so we cant do anything now. Being a customer care they also are in favor with workshop.
Even if it is one year if this part was not fitted properly then whose fault it is?? Skoda has given them franchise. Is it like this if they have not done proper work and due to there not fitted properly after one year we found then customer has to bear or what??
Presently also when the headlamp is fitted it looks normal so why will anyone open. But we given request to change for led fade which normally cant be.
We even told that we will complaint to consumer still no effect on them. I have some clues also regarding this issue and other issue also which can show there mistake.
