Kpn Travels — late drop

I have booked ticket from chennai to pollachi for the date of 11/09/2018 (09:45pm) in non a/c sleeper bus. The bus came one hour late to perungulathur and it is already three hours late and bus still dint reach pollachi. The bus slow even where the routes are free. I have really a bad experience with kpn travels and all my plans have been spoiled and the purpose i came to pollachi has not been done due to your late drop. I will never again book ticket in kpn travels and also will tell all of well wishers not to book in kpn. Really irritating with your timings and all other buses which started after this has already reached pollachi. Its so unfare that you are not bothered about the timings and the customers. Thanks a lot kpn for spoling my work.
