Your blog was so simple, I went ahead and created one too, thank you.
It is the collector's job to get you to "admit" that you owe "him" an alleged debt, but you must force him to "prove" that you owe him money and he cannot prove it.
When the collector is forced to write you a letter, send a copy of the letter back with your letter "demanding proof" and send it by registered mail with a return receipt.
