Fraud company

I booked a bus via redbus as early as 3am. After running around trying to figure out if the bus is missed and profusely sweating got to know after innumerable calls that the service got cancelled without prior notice. They should have been a little more considerate towards updates. After this comes the issue of refund. Once they call me and say that I would recieve a full refund into my bank account and the same day they say charges will be deducted for booking the bus. I don’t understand why customers should pay GST without availing the service. Simply they are deducting mediator charges and burdening customers. I’m so upset with this open kind of cheating.
