Here we go again!!!

I got a settlement letter from the attorneys office that is handling my account with Citibank Mastercard. The original date for the court hearing was 8/6 but I got a letter from them saying that they needed the money by 7/30. However, the woman that I spoke to told me that it wasn't due until 8/5. A few weeks later I got a letter from them telling me that the settlement offer was good until 8/15. If it wasn't in by that date, the offer would be retracted. I just got a call from their paralegal asking me if I had the money for the settlement b/c the court hearing is tomorrow. I told him that I got a letter stating that I had until the 15th of August to have the money in. What can I do? Does Citibank still have a case against me being that they goofed on the letters
