I have financed a bajaj avanger bike from bajaj auto finance for 12 emi i already paid 10 emi on time by pnb bank ecs. Have issue in last ecs that it was deducted on 6 feb by my account but still i got messages from bajaj finance that my ecs was bounce but i were confirm in my bank and also sent mail bajaj auto finance on 9 feb with my bank statement and talk many times with customer care executive or also with senior executive but every time they give me different answers.
