Can I sue a bank for damaging my credit?

Capital One sent me a letter demanding my W9 for a bank account which I did not own. They said I was currently in backup withholding and threatened to turn me over to the IRS. I replied saying that I do not have an account, have no plans to open one, and if someone used my name to open this account close it and report it as fraud. Capital One responded by canceling both of my Visa cards. I responded by filing a complaint with the Federal Reserve. The Fed forwarded my complaint to Consumer Fiance. Capital One responded that the account was opened by my landlord to pay interest on my security deposit, all without my knowledge. I responded that they failed to notify me in writing, closed both of my Visa accounts permanently, and still owes me about $25 for a credit balance. I do not know the amount of interest which was earned, but it is likely less than $50 and not worthy of a W9 form. I wish to be compensated for damages to my credit and failure to put any of this in writing.
