Check your balance carefully if your transactions are very frequent.I noticed my account get debited without my knowledge, and when I complained, the bank reinstated the amount in my account. it happened twice.My friend also noticed such an incident happening in his account.
One day he came crying that Rs 10000/-is missing from his account and rushed into the bank, and the bank authorities solved the issue by newly depositing Rs 10000/- to his account thus he got the money reinstated. Actually if the amount were smaller he might not have noticed it.We never expect such things in scheduled or nationalized banks. But I had heard that new generation banks do have such malpractices, and I experienced it.
So frequent, careless users may please be cautious about it.And those who had the same experience may please intimate it.
