TSRTC — Maintenance

I am traveling from Khammam to hyderabad in Rajadhani (AC) TS04Z0201 bus with a Fare of Rs. 500 which is higher than fare of normal busses because it is air-conditioned. BUT After 30mins of journey, the AC stopped working. It is suffocating heavily and there are many small babies traveling in the bus that they are unable to breathe properly due to suffocation as there is no chance to open the windows for ac busses...this is really worst maintenance ever and my fare of Rs. 500 gone waste and moreover I am having a troublesome travel. There is no minimum cleanliness in the bus..This is not at allll fair with TSRTC that there is no minimum check before the start of journey..
