Girls religion after marriage is ulterable or not. Just want to know

I am Rachna Rohilla hindu by birth and I have done intercaste marriage in Jat caste. My Rohilla community has a caste base agency type which provides loans to rohilla's on low interest rate and every month we deposits some amount called cd in our account. They have provided us passbook type copy also where they make records or our CDs and loans. But now agency is going to cancel my account because I have done intercaste marriage as per them am not Rohilla anymore. But I have read that supreme court says marriage cannot change relegion of girl. I just want to know they can cancel my account or not
