Telangana State Road Transport Corporation [TSRTC] — Questionable behaviour of driver

I boarded tsrtc Garuda bus with SERVICE NUMBER 1298 from Bangalore to kurnool scheduled at 8.15 a.m
1. I got a call from driver at 7.55 a.m yelling at my why I am not there at the bus stand yet. When the departure is at 8.15 a.m, I had 20 more minutes in hand and I was at the busy stand
2. Secondly, there was a stop at anantapur. I told him that I will be going to washroom and he told me to be back in 5 minutes. It was less than 5 minutes and the bus went away from the station without seeing if I was back or not even though I informed him and went.

This ### behaviour is not tolerable and I will never book another Garuda again
