Godrej Properties — Unauthorized penalty charges on payment

I have received a "reminder -1" related to the payment delay which was due on24th August that a penalty of 5, 048.10

Based on frequent and recurring chases and discussions with CRM and Godrej finance banker "the NOC was pending at builder side" and nothing was remaining at my(client) side".

Below is the summary :
Have received the payment intimation on 18th August 2022.

Have started frequent and recurring calls to Godrej finance banker since 18th August as payment was due on24th August.

Banker told that NOC was pending at the Builder's side for one month.

Have started frequent and recurring calls to CRM since 20th August as payment was due on 24th August, she told me that handover is in progress as the previous CRM has left the company.

Both banker and CRM were assuring that no penalty will be incurred by the customer .But still recieved the penalty letter.
