MakeMyTrip — wrong information, cheating, no response

my booking ID is IN1208B16173. I wanted to book standard mini kerala package (given on internet) with small modification in pick up time at alleppey. I contacted for the same to Swati gupta (Swati.[protected]@makemytrip.com). She send some itinerary but I did not bother to go through as I have already seen the itinerary at the internet. I said OK and paid for the booking (She said I will get discount as well). When she send me the hotel vouchers then I came to know that she has allotted me a hotel of lower star rating than what is promised on internet. I asked to change the hotel to the one shown on internet. She refused to do so. Then I asked for cancellation as I want what I have asked for. If you go through our email communication it will get clear that I never asked for any modification. Thereafter, I was directed to communicate to her supervisor Mr. Birender Rawat. I tried to speak to him on phone but he didnot come to phone. I also asked om mail to give me a call, he never bothered to do that. He said my issue will be resolved in 24 hrs. I had already paid by then Rs. 21110/-. I checked on internet the package I wanted cost me on internet 21498/-. They are not taking any action on my request and I have got no communication from their side.
please do the needful.
