Hi, Query #1:- Bank debited the amount saying 100195.56 & 8219.44 on 14/12/15 & 16/12/15 rasp without any information or intimation from bank so bank should inform to the customer if debit the amount from customer account. Query #2:- I am taking multiple follow up for the same from last more than 10 days but still the amount has not been reverted back to my saving account. Query #3:- I have loan due amount around 68000 on my ready credit account so ideally bank should debit the due amount + interest on it for that month but bank debited the extra amount from my saving account Query #4:- Bank again debited the loan amount 69309 from my saving account on 23/12/15 but ideally it should be adjust with amount already debited from my account & revert back access amount in my account. So please suggest when access amount will revert back in my account.
