Kpn Travels — worst response and delay

I booked kpn travels bus from perungalathur to trippur today.
I was dropped to vandalur and i am waiting here for more than 3 hours.
When i called to perungalathur office, they attended the call and didn't respond properly.
This not the first time, many times i have booked kpn travels.
Worst service i have ever seen.
Definitely i won't suggest others to use this kpn travels.
I even tried calling kpn head office, salem, but no one picked up the call.
I don't know why the customer care phone number is available.
Is it available just to update in website or really care for the customer?
