Oyo Rooms — pathetic customer service

We recently stayed at Hotel NNP grand in Rameshwaram. It was terrible experience and wanted to highlight the issues :

1) Mattress in the room were terrible and in really bad shape. We had back pains because of the mattress.

2) There were Rats in the room and they jumped on us while we were asleep in the night.

3) The towels were so old that they had turned into dirty yellow color and hotel staff had used so much bleach to clean them that they have become hard and towel felt like spines when used.

4) We had one room booked for 3 people but there no arrangement for spare bed.

The hotel was not all worth the price charged. Hope some action would be taken and we would get refund. We tried to contact OYO but no proper resolution has been provided.
