Can SBI bank take custody of hypothecated vehicle for 1 EMI's Due?

Hi there, Sir wanted to ask one this please read the below i have taken a home loan in month of may 2017 i cleared 3 emis from the day that i have taken after a while in october i have taken a car loan for my ertiga which i have cleared 1 emi and the bank came on 20 dec and took my car away called me to the bank and said that you home loan is np account and that s the reason why we are also taking the car cos there was no emi paid i have paid the emi on 19th of dec and the car was seized on 20th. The letter says that the bank has fully rights to seize the vehicle and if it is not cleared in a week they can sell the vehicle. I have been getting calls asking to clear my home loan but i have informed them as you have siezied the home you have the right to sell the house but what about my car as emi has been paid without any delay. they said if one account goes np the other automatically goes and thats why they have seized the vehicle. i have contacted the branch and the manager says if one assest is not clear they cannot seize the other which is clear hence you should as per law should get your vehicle back but not home. I dont know what to do please if someone can give me clear picture regarding this. The manager says that he will try to get the vehicle back but not sure about if i will get it or no. regards, mohammed
