Bank of America is awful!!!!

I have no idea what to do. I had one b of a checking account that due to pros became severly overdrawn. I had another checking account with them and they keep transferring money to cover the overdrawn balance. The first time it happened they said it was their right and they were going to do it until the overdrawn account was clear. I asked if I'd be notified and they said no. They are doing it again and I have several outstanding checks. Also I am extremely. Sick and my neurosurgeon may send me to the ER today but I don't want to go because I have no money! Will they work with me at all on this? Maybe let me set up a payment plan instead of just wiping my account out? I'm so frustrated because I work hard for my money and have very little. Also, I don't know where else to go for an account because of chexsystems! Please help! I'm trying to get everything paid off but b of a is making it impossible!
