Canara Bank — Unknown money deduction

Address:

Canara bank, Perambalur

I took car loan from the Canara Bank Perambalur branch.
Account number :[protected]

I am regularly paying the EMI on due date without fail.

In my account if i have any amount available it is getting deducted from my account.
So because of that i used to maintain balance only on the due date.
Similarly this also i have maintained EMI amount on the due date. Surprisingly amount got deducted but EMI is partially paid and around 16000 is lost from my account.Now balance amount is zero.
These kind o[censored]nknown transaction are getting repeated and everytime we have to report it back.
Even after deducting amount, my loan account is showing pending due along with penalty.

For the purpose of security we are preferring nationalized banks and this kind of activities are not at all acceptable.

We have to run behind the account details to check what is happening. I don't understand what is going wrong.
