Can it possible two number loans on same property,borrower and bank and one is npa and other normal

I have taken a home loan from one pvt bank for 5 lacs and then taken more loan as top up but they have allotted different account number to complete their numbers target. usually i was paying both emi simultaneously. there was a break for few months as i lost my private job. when i approach again with emi they taken later one bur refused former one. they said they have given to some asset reconstruction company. when i approach them they have not given anything in writing .they were charging very high interest etc.but in reality out of 5 lacs i paid 4.88 lacs including interest. the other account is normal and i am paying emi every month. they enforce sarfaisi in my earlier account and gave me notice .i offer them half amount and send him cheques,but they refused and want full amount around 7 lacs ,which is not fair. what are remedies/options are with me, because interest is increasing.how i can i pressurise them for one time settlement. they are not listening me and they are spoiling my cibil also.
