Pay U Money — account debited even when transaction is failed

Sir, i was purchasing an video course (Bank prime) from adda 247 yesterday through your pay u money but my transaction failed in the end of process. I tried thrice but got the same message saying "transaction failed". But my account is debited thrice by 14997. When i have not bought anything then why my account is debited even when the transaction failed. I have confirmed from my bank that the amount has been transferred to you. So, it's my humble request to refund the amount debited.
My payment ids' are -
