MakeMyTrip India — wrong booking voucher no response

I booked 3 rooms for 10 guests (6 adults and 4 children) for 21st-23rd dec in four points by sheraton, mahabalipuram through the makemytrip app. I wanted to change the dates of travel. I tried contacting makemytrip, the automated response received was we are attending to customers who are travelling in the next 10days because they are short of staff. The prices are going up on the other hand which they do not realise. It is our money that is at stake. The automated reply said do it on the app or our website. I then went to my booking on the app, it had a few options like cancel booking, modify guests, modify dates, etc. I only clicked on modify dates and selected 27-29th dec. It showed a that your package is available for your chosen dates for a price difference of rs11000. I then paid the differential amount and received the new booking voucher. Please note the new voucher is with only 6 adults and 0 children. How can this be? I have clicked on nothing other than modify dates.

2nd phase
Withing 10 minutes of recieving the voucher i was trying to contact mmt. My fear is i have now paid rs82000 and at hotel they might ask me to pay more for the children. I was unable to cancel and make a fresh booking also. I messaged frantically through my app. I finally get a call with maybe 2 rings late in the evening which i missed. I then get a message saying case closed. I do the chat process again. I finally get a call and the agent says yes there is an issue with your booking, our specialised technical team will get back to you maximum with 48 hrs. I was slightly relieved. But after 24 hrs i got impatient again because if i have to cancel this booking and make a new one, the prices are soaring high. I chat again, get a call and say the same thing, there is an issue we will get back.
Please note that it has been 5 days for the first booking and 4 days for the second. There has been no response at all!! I wanted to file a case as i'm feeling harassed. My money is involved and other two families whom i don't know what to answer.
If they want to cancel my booking let them do so and refund my entire money or call me to discuss. I have both vouchers to show which i am unable to upload
