Indian Railways — travel discomfort

I traveled on 17th march from ahmedabad to mumbai pnr [protected]. Rac39, b7. The ticket checker confirmed berths for numbers after mine. Except for two passengers of rac39 all in b7 got berths. I also saw that one lady who was probably not even rac was allotted a berth who came to our compartment much after the train left from ahmedabad before the next station. Whole night i sat without a blanket in a. C. With my severe back ache. I had dialled 138 where i was told to speak to the tc and i requested the tc but according to him there were no berthsavailable.
Please check this matter.
At the age of 57 with pain in my back due to joint pains, gout, i sat throughout the journey very uncomfortably even after paying full money for a berth in a. C class.
