Telangana State Road Transport Corporation [TSRTC] — bus missed because of drivers phone switched off

I had reserved a seat in super luxury bus having service no 8034 on 28.10.2017, 3 pm from mgbs to mancherial. I had called the driver on given mob no but it seems switched off.
As told your enquiry counter i was sat on platforms no 53 but bus coming on another platform no and departed without giving any intimation.
The driver called me after one hour from jubilee bus stand (Jbs) to say bus departed.
If he called me on mgbs itself bus will not missed ever. And a shame thingis that tsrtc managers are also not supportive. They couldn't help on such matter.
I requested you to please update your system to avoid such issues.
