IDBI Bank — property inspection charges after 3 years of loan disbursement without notice

Address:

411045

Idbi has charged me around 700 rs and directly debited the amount from my account without giving any prior information or notice, i dont understand on what basis they have changed this to my home loan account now after 3 years of loan disbursement, i have written the concern to pune home loan office multiple times and even escalated to grievance redressal officers tier 11 but they are not even acknowledging the mail on this context and responding to me.
How can bank directly deduct money without informing customer, the direct debit should be the only emi amount and nothing else.
I would request bank to pls revert amount back to my account since i haven’t got any such mail or letter notifying the same and moreover its 3 year old loan account disbursement.
