Bajaj Finserv — loan charges

Address:

159 Kennedy's 3rd line oorgaum Post kgf kolar, 563120

Loan account no: 5i2gtl62876483
I cleared the above loan 2 years back but yet it is not closed, i paid all my emi's on date whereas only one emi got delayed and twice cheque bounce charge was deducted from my account. Now again i received a message from finserv quoting 350 cheque bounce charge outstanding, please verify and resolve the issue at the earliest and close my loan.
And when i try to get to login into my account its showing dob mismatch, my original dob is 20/09/1986 but i don't know what is on database. Please resolve this issue also.
Thank you,
With regards,
Tarzan w
