Legal debt validation follow up letter for a collection agency. My rights by law

Just an update I hope that's okay.
I looked up the actual FDCPA 801 (b) outlined in the debt validation letter. I decided to submit one last letter the collection agency outlining to them the actual documentation required under the act which I know now they cannot provide to me. I hope this letter will help to avoid involving any other agencies. I feel its worth a shot.
A lawyer actually wrote this letter and I found it on the web.
I am submitting a copy of the letter to you in case other people don't want to file with government agencies for assistance.
Perhaps I'm overstepping my bounds but I hope you will consider using this in your website as a second response letter to the first if folks can't get what they are seeking. I'll let you know how it turns out.

Thanks again for all the info and for your tremendous website!
