Kpn Travels — most convenient travel

This is my first trip with kpn travels from chennai to bangalore. The seat i chose had lost its spring tension that when i reclined it went down flat. I could not use the recline option and had to sit upright all the 7hours of my journey. The curtains that were put up on the window panel must have been washed about three or four years back that it was so sticky and had a bad smell emanating from it. There was some electrical fault in the driving panel that a beep sound was coming from the vehicle continuously through out the journey that i developed severe headache. Is it not the basic duty of the company to check these things from time to time so that they do some justice to the fares collected from the customers?? I only hope the company takes this complaint seriously and acts upon it to provide a pleasant journey to its customers like me so that my first trip with them does not become the last one too.
