On[protected], my cheque no. 393979 is dishonoured and amount 177 has been deducted. After some time cheque no. 393978 is dishonoured and amount rs. 590 has been deducted. After some time cheque no. 393.979 is cleared. I am unable to understand these irregularities and dishonour of customer.
1. How penalty of dishonour of cheques of same amount, same bank and same time are different.
2. Let me know the cause behind cheque dishonour.
3. Incharge manager of branch is saying, 'come after 15 days, our manager is on training'.
