Bajaj Finserv — Amount of Rs 707/- debited owing to cmp mandate

I noticed that amount of rs 707/- was debited towards cmp mandate for Bajaj Finserv. I have recently purchased a mobile online on zero cost emi. And every month emi is being paid but now another amount of 707/- has deduction and also it is going to continue till my last emi. Why?
In my previous purchase as long installments were paid every month even during lockdown but no certain amount as cmp mandate was deducted by then.
I have been customer of Bajaj since 2005 and this has never happened.
Kindly clarify and cancel this cmp mandate as soon as possible
