I understand you think you're very tough and you think that by dragging this process out you have created me a lot of misery; that is an incorrect assessment, but I must admit I have run out of patience with you and your smug attitude.
If you resolve this issue quickly and efficiently I can guarantee you will not hear from me again; if you don't, well, you will be well known to the Citibank customers you are currently in litigation with in a very short amount of time.
PS: I took the liberty of buying the corporate phone directory and locating information on your outstanding disputed credit accounts from an internet dealer today, and can probably make you better known to your customers than the security measures you enact at your company indicate you would like.
