Bajaj Finserv — cpp tele binding bajaj finserv

Kindly note self bought ac (For donating to the local hospital) from the verma electronics nabha (Dist patiala, punjab)
Loan was availed for the sum inr 14000 for 08 month at 0.0% interest, thus costing inr 1750 month.
As i am retired, and not a technology person, have not been touch with the e-banking mode.

My son (Serving in navy) has checked just casually on my behalf about the details of the emis.
And to my surprise, i have been deducted inr[protected]+508) every month for past 6 months.

On enquiry to my surprise again the charges inr 508 every month was incurred for the cpp tele binding loan/insurance availed.

So concluding,
1. I have not registered/acknowledged any sms or call for such service.
2. A question to the your good firm. How can you just fix/approve a loan over a phone? There can be a chance when i am not speaking over the phone or my phone has been lost? Is it really legit or logical?

Kindly do the needful to reimburse the amount paid so far for the service i have never availed/ or acknowledged.

I am your sincere customer past years. Kindly speedy acknowledge the email.

Thanks and best regards
