Bajaj Finserv — Additional amount charged

Address:

Kolkata, West Bengal, 700106

I purchased a Washing Machine on 25/10/2011 worth Rs 12400, paid Rs 4600 and remaining amount was financed by Bajaj Finserv( Loan No. 4100CD[protected]
Due to insufficient account balance all the installments were collected in cash.
There was a dispute after paying all the installments. We went to your office and settled it by paying Rs.2650 (Receipt No.[protected] and secured a NOC on 29/11/2013. I never secured any loan from Bajaj Finserv after the matter was settled.
I never received any call reguarding any dues.
On 15/01/2016, I got a call and I was told that an amount of Rs 54000 was due and got a message that my EMI card, which I never received was suspended and will be activated once I pay 3 installments.
I complained at [protected]@bajajfinserv.in
They claim that an amount of Rs. 62, 936 is due under "BALIC PREMIUM CD LOAN", loan number 410BAL00210326.
I have no idea what is going on.
