Mobikwik — extra amount charged in railway ticket booking

On 9th march 2019, i booked a railway ticket and made a transaction through mobiwik app. The fare is rs 3250/- but the amount deducted is rs 3319.03.

I have attached images of booked tickets and invoice from mobikwik for your reference.

Please do the needful in this regard and help me to get refunded extra amount charged by mobikwik, into my bank account.
