Mobikwik — amount not credited

My bank account got debited for am of 833 on 6.4.2018 at 1pm. But my mobikwik wallet didnt reflect any amount nor did my recharge was done. I need refund of the amount as soon as possible. And neither mobikwik history shows any transaction as to whether the payment is done or failed.. Neither there is any message for payment successful nor for payment failed.. Just my bank ac got debited where is my money??
