Cleartrip.com — Payment scam

I had a problem with my booking, trip ID [protected]. Because the price was almost doubled AFTER I pressed the pay now button, I was of course not satisfied. Therefore I did not want to go to the hotel. What should I have done? There were two options, money back, but Cleartrip takes a big fee for booking back my money. Of course I am also not satisfied with this option, as it was probably a software error. In addition to the 300 RS Cleartrip fee comes the conversion charges of my credit card company. Another option could be to put it into the Wallet, a new feature on Cleartrip. Of course I carefully studied the rules for about an hour. But I did not find that I would not be able to use it with train bookings. Because this is the only division of Cleartrip I am reasonably satisfied with, you should have warned beforehand. On the basis of this incomplete information and the panic of the moment, I had only a few minutes to cancel the hotel, I decided to cancel the hotel and use the new Wallet feature.
-Please refund my money to my credit card number, because you increased the price making a price agreement with me (after I pushed the pay button, which sends the details to my credit card company).
-Please make clear your rules for coupons. And absolutely warn when a coupon is used before, that is before the customer gives permission to take the money from the credit card.
-Please, remove the software error. I did see the error because I am very careful and conscientious with my payments and always triple check, but many other customer might not see it, and would pay much more than they thought. I would put this under the category of fraud (maybe unintentional, but if so correct your error).
Until these things have been solved and/or answered I will be extremely hesitant to use the Cleartrip services.
