I wrote a check that did not clear, but was unaware as the business I wrote it to never contacted me. I did find out by receiving a letter from the district attorney's office in my county, charging me for the amount of the check, fees and then 100.00 for a school that they wanted me to attend. They threatened to send me to jail if I did not respond. I emailed with no response and then called several times to get clarity and left messages. I finally wrote a letter and explained that I had never been contacted by the business and had not knowingly wrote a bad check and that I do not have a history of doing so in the county. I stated that I would pay what I owed the business, plus fees, but that I did not feel I should have to pay for a class they wanted me to attend. I sent in the final amount in January and heard nothing from the district attorney, so I assumed all was done. I just received a letter today - May 5 stated that I still owe and they now added 30.00 more in late fees. What are my rights in this situation?
