Club Holizone - Misguiding customer and false commitment

I received a call for company free offer for *N/*Days for Fort Pachewar. We go to GIP mall Noida to get more detail. We met Mr Sumit Jhanji with one more junior. They show us *-* star hotels on a booklet whose online pricing was more than *k-*k/night. They offered the *-year plan for xxxxxx INR with complementary *N/*Days (with breakfast+Lunch+Dinner) fort pachewar Jaipur. We asked them to give more time to think about this but these guys pressurize that offer is valid for today only. We said we don't have money then they said they will convert complete amount to interest-free EMI for two years. I did the biggest mistake & made the payment.
Now the story began. I call them for interest-free EMI then they said I will receive a call from the bank. I did not receive any call from bank & finally, Mr Sumit Jhajhi asked me to convert the amount into EMI by myself. He assures me of mail that my company will refund the interest amount. We made the payment on **-**-****. But even today they have not refunded my amount. I am totally frustrated with these guys. Every time they commit a date but never stand on their words.
I was in very painful situation when I saw the hotel list. **% Hotel has priced up to *k/night. I send a mail for the same but they did not reply on that. At the time of payment, they show a list of the hotel which has pricing of *k-*k/night.
The last thing they called us to promote their property Fort pachewar (Jaipur). But now they have cancelled this offer by saying that it is under maintenance. In replacement for that, they are offering a much lower price hotel.
I am totally frustrated with these guys. I don't want to use any service from this company. I want my full money refund.
