Fnb holding a gun to my head to pay joint homeloan

The worst bank ever l called fnb because im trying to get my name removed from a joint bond for years now and they cannot assist. The answer is simple if the other person doesnt qualify u won't be removed even though I don't stay there even though my account is not debited even though I said l can't afford that property and only did it to help the person qualify fnb homeloans is holding a gun to my head with no way out even though i told them my kids and i dont have a place to stay they dont care they need someone as back up when the other person cannot pay. All the other banks have a simple process fnb is selfish and greedy and thats why i will never recommend them to anyone. I am being used as bait because the other owner pays late or skips a few payments so they refuse to remove me but they shoudnt call me on payments because I can't even afford another place now how the hell will i pay a bond where i don't stay. Fnb should stop exploiting the poor for their selfish reasons
