Can i sue bank of america ?

I want to sue Bank of America for defamation. A year or 2 ago i had an account there. I over drafted it a few times here and there, but i always paid my debts. One day i wrote a check to them from my other WaMu account, to pay an overdraft of $50 or so. I had money at wamu but it was still pending or something and so the check bounced. Bank of America then immediately closed my account. Then, i get a notice that i have been submitted to chex systems. I look up why I am in it and it says” Check Fraud”. This single bounced check would not and does not constitute check fraud. Now thanks to this, my credit is messed up and i cannot for the life of me open a bank account. I have no way to deposit checks without paying fees to stupid check cashing businesses. Do you think that i could sue them for this ?
