Make My Trip Gurugram Haryana India - Check in denied

Booking was made to Johnson Lodge Manali for **th April stay for * night reservation before **th March. After ** days of reservation, I got a call from makemytrip Johnson has a change of Manaagement and as they denied checkins, they will provide cancellation with full refund or other hotels.

I requested if they can talk to new management and I can get the same property. Exectuive of makemy trip said it may take * to * working days which was confirmed by me should be fine.

After * days, I have made multiple calls mentioning the below reasons:
*. Executive working on this case is going to call back
*. You don't have to worry as we have arranged a call back and you will surely get a call back between * to *
*. Asking for the supervisor to escalate supervisor is not available in this shift
*. What supervisor is going to say should be the same you have to wait

Fed up of this kind of a treatment where I did the prior reservations if I would have got the check in denied on the same day, wonder how they would have treated.
