Punjab National Bank Housing Finance [Pnbhfl] — loan principal amount increased without any information

Address:

Pune

I am a loan holder of pnb housing finance.
I just have received my loan account statement and their it is reflecting that my principle amount increased by 2 lacs.
How could it possible? Principle amount increase is depends on my own approval.
I have opted moratorium in lockdown period, but as per them the interest rate will calculate extra and accordingly they shared with me current emi increase details. But how come they can increase principle amount without informing
