Telangana State Road Transport Corporation [TSRTC] — Few buses from kachiguda-Apurupa colony

There were many buses before from kachiguda to apurupa colony, route 83j/a.
But from few days there was constant decrease in this route buses, many students and employees live in this side of the city and travel through 83j/a to reach destinations as panjagutta, ameerpet, khairthabad and lakdikapool. And 83j/a is also the only bus which directly goes to liberty, himayat nagar, Secretariat stops from jeedimetla side. And these route buses obviously be rushed with people, but don't know why only few buses are coming nowadays and not even on time. So i request the management please provide more buses on this route especially on evening times.
