I booked a bus ticket from make my trip on 26th february of inr 591, through internet banking. Amount was deducted from my sbi account but the ticket was not booked, but make my trip claims that they did not receive even though my bank - sbi
Confirms that amount has been transferred to their account on 26th february. If transaction id. Has been generated that means amount has been transferred to make my trip. But they are not accepting that amount is transferred and continuously asking me to contact my bank.
How can they cheat like this. They are not accepting due lack of will to transfer back the money. Please refund the money back to my account as soon as possible
