Bajaj Finserv — Personal loan - plcs small ticket size part payment charges

Hi Team,

I have Bajaj Finserv PLCS SMALL TICKET SIZE Personal Loan.
On Bajaj website, it is mentioned that for "Nil Part payment charges if the total amount paid in year is less than 25% of the principal outstanding".
However, CSR person saying they have not applicable option such.

Could you please help to confirm the Part Payment charges for less than 25% of the principal outstanding.
