Indus Motors — service issue repair

I am using maruthi vitara brezza since 2017 october 30. I am writing this complaint to bring your attention into an important matter. My vehicle number is kl-07-cl-8344. I have done my second last service about 8 months before at kalamassery indus motors. During that service the advisor found an issue with the horn and he said i will get the replacement as soon as possible and it was under warranty. And i am very sorry to say that till now i didnot get replacement of the item. Its been 8 months and i contacted them several times. The main concern is that is my vehicles warranty period will end up on this coming october 30. So i kindly request you to make immediate arrangement to get the replacement of the item because its only 10 days more to end up the warranty.

One more thing that i was thinking about adding extended warranty by paying the amount. But how can i get the benefit. Beacuase maruthi indus is not efficient to get an item replaced since it is under normal warranty.
