I recently received a letter from a law firm saying I owed them money. The letter was very short, just 3 sentences long, just saying the amount I owed and to make any payments to them. In the heading, it mentioned a company, Midland Funding, which I had never heard of, so I looked them up and saw that the company buys charged off accounts from credit card companies and then attempts to collect the money themselves. After reading this, I have a feeling this had to do with a credit card I had years ago that was charged off.
