I want to inform you that unauthorized charges are deducted from my bank account. I have cleared my loan on 30/04/2019 but after clearing my loan still charges are deducting from my bank account in the name of ach rtn charges.
Whenever i deposit cash in my bank account some amount of cash got deducted for ach rtn charges but i have already cleared my loan then why this type o[censored]nauthorized transaction are going on my account. This is unacceptable and for this reason i cant make deposits in my bank account.
The details of transaction are as follows and same is attached for your reference:-

Txn date:- txn amt (Inr)
02/05/2019 90.00
10/06/2019 500.00
10/06/2019 500.00
24/06/2019 2.00
23/10/2019 47.90

Loan details-
Capital first
Loan a/c no[protected]
Either capital first (Idfc first bank) nor idbi bank, no one is accepting the fault then who is responsible for this ridiculous job?
Please solve the said issue as soon as possible and if possible then please make refund o[censored]nauthorized deduction. Supporting documents and bank statement is attached for your reference.
