They cannot be reliable in matter of hotel bookings.
It happened with me for Havelock Island Hotel booking.
I did paid the full booking amount at makemytrip for the booking but when I called the property to confirm the booking, and to my surprise I get to know that they havent received any booking, then I had to book directly through hotel.
I even saw a couple who waited almost for 4 hours at reception, and they had to book directly at property.
As connectivity is the major issue there, then how will a person reach out to MMT CC in such situation.
I am never gonna use MMT for hotel bookings anymore.
