Ibibo Group / Goibibo — Did not provide an alternate hotel, when the check-in was denied because the hotel was not operational

I contacted goibibo to inform the hotel denied check-in for my upcoming international travel which is in a week. From 7 days they kept giving excuses that they are not able to contact Maldives government and this and that. Ultimately they stopped responding to me and just ignored the issue. They didn't provide me with an alternate hotel although they told on day 1 that they will shift me to another hotel without any extra charge. Now they just don't respond. I have to book a hotel 1 week ahead of my travel at 4 times the price I paid when I booked 5 months back. Who is responsible for this issue? They still didn't remove the hotel that's not operational from their website .
