Dell India — audio system and keyboard

I purchased a dell inspiron 15 5000 series on 29th june 2017 and after 2 months of purchase the audio system and the keyboard was damaged and it has a 1 year warranty and only 7 months are only remaining and we tried and called the customer care number and they answered the call and after few minutes they ended the call. We tried and called 5 to 6 times but they did the same because of the problem we are facing a lot of problem and we are not able to do anything important on the laptop. So, we request you to please come and repair the laptop.
