Indian Railway Catering & Tourism Corporation [IRCTC] — worst housekeeping/cleanliness

I was travelling in jaipur chennai express trn no - 12968 on 31st december in ac first class compartment and i would like to highlight that cleanliness was worst and the behaviour of attendant was also very rude and arrogant. I had boarded the train in nagpur and to my surprise, i found used bedsheets, blanket, pillow and napkin on my berth. I had waited for the 1st class ac attendant to clean up the mess and provide me with the new set of pillow, blanket and bedsheets but to my surprise, i had to remind him of his duties. And moreover, one attendant is telling me to use the same blanket which was lying on the birth. I was shocked to see his behaviour and ordered him to replace everything. Then after some time, he got new set of blanket, bedsheets, pillow and napkin. But the horror is not yet over. The real game starts at 10 pm. I was sleeping like anyone else in the compartment and to my horror, i found lot of bedbugs in the blanket. From 10 pm till 1.30 am i was ignoring thinking it to be mosquito bitings but was shocked to see so many bedbugs. I didn't have one hour sleep also throughout the night. Even the attender was happily sleeping in his place. I had booked the ticket in 1st class ac compartment to make my trip to be very comfortable but to my horror and anguish, it was my worst ever train trip till date. I hope the northwestern railway look into this issue at the earliest so that passengers travelling need not have to face the wrath which i had faced. I was travelling with my mother and she had berth in 2nd ac. So i went there in the morning till the time chennai central arrive.in the end, the same attender is shamelessly asking me thinking that i had kept the napkin with myself. We are not travelling in train to steal the things given to us for our use but we expect the highest cleanliness so that the trip is memorable. I have attached the photo and video of bedbug for everyone to see.
