Indian Bank — money debited into account

I have a saving joint account ([protected]) with my wife name in thudiyallur branch at tamilnadu and today morning my wife inserted the atm card in the tamilnadu mercantile bank at kanuvai, coimbatore branch, tamilnadu but the amount (Rs. 5000) debited in the account but not received from the atm machine and immediately she informed the same to the mercantile bank and they told some time it will happened like this but again it will credit to your account.

As of now we didn't receive the amount back, so kindly check and credit back to the account and please inform to us by mobile ([protected]) otherwise by mail "[protected]@gmail.com"

Thanks
