Indian Railways — AC rail coach on train no 16527 date[protected]

Date[protected]. Train no 16527 from ypr to kannur. Pnr no [protected]. Coach no 99144-b2 and bert no 55
I took the above train to kannur and at about 10pm i found my entire blanket was wet and on investigation found that due to rain water was leasking through the sealed window. This was noticed on all side berth.
This was brought to the notice of the coach tt who arranged for fresh set of blankets. Fortunately the rain stopped and i could sleep after 11.0pm.
I wonder how this lapse could occur in a c coach inspite of paying higher charge. Its very well known that coaches for this region is of very poor condition and hope the concerned will take action. I plan to return to blore on 1st may by the same train and do not want repeat
Thanks
