Citibank — Premiermiles fraud

I would like to bring forward the fraud that's been happening under the Citibank premiermiles which is handled by goibibo. I have over 2 lakhs reward points under my card which I had to redeem under premiermiles. I was trying to book hotel from their list but to my disbelief all the prominent hotels were sold out by default no matter whatever dates we put. I had raised this issue in Jan 2021 to their team which they claimed to be working on. Recently i tried again and was facing the same issue of the default "we are sold out" irrespective of the date of booking. This is in particularly with 5 star hotels only. So I again communicated it to their team. They reverted saying that it was a technical glitch at first and upon confronting them over the phone they sent me an email stating those hotels are not listed. I replied demanding why have they still listed making it look as though its available. On one hand they are encouraging to use the credit card for points and yet we r unable to redeem it.
