2. on 30.8.2021, I tried to order 1item from Amazon of rupees 938 through my bank of India debit (transaction id-MEDR/ WWW AMAZON I/333981/).but some issues Amazon shows payment failed, but that 938 rupees debited from my account.

But above 2 transaction of same amount of money (on 24.8.2021 debited amount 938 & 30.8.2021 debited amount938), I received just one time 938 rupees in my account on 1.9.2021(MEVR/000000/[protected]/VO4/VISI/) . Another amount of 938 rupees is still not received in my account.
