Indian Railways — bed bugs on my berth

I am engineering student studying at chennai. I boarded a train from visakhapatnam on 18th september 2017 in howrah - mas mail sf express (12839) in a 2 tier ac coach. I thought my journey would be peaceful until i discovered bed bugs crawling on curtains and lying inside carpets. I had no sleep at all that night and when i came to complain about this to the cleaner and carpet man they refused to respond and instead they were asking for money, they also even refused to tell where the ticket collector was, they were not all bothered that too in a 2 tier ac coach. Irctc charged me rs 2065 for payment of ticket and i was happy at beginning that i was going to board 2 tier ac for the first time. I sincerely request you to take immediate action on this, i would also like to have a refund. The impact of bed bugs had a disastrous effect such that i couldn't attend the exam on that day also i was unable to travel in this train due to sudden jerks and worst maintenance. This is the worst journey ever in my life.
