What do I do if I have a failure to appear but I was never given a court date?

I went to court after being pulled over and thought everything was fine. I was pulled over 5 months later and was arrested due to a warrant and I'm still not sure how I got the warrant even after going to court for charges. I paid a $500 cash only bond and was told I'd have a court date I needed to go to in order to clear everything up. I never received a letter and I called today (it’s been about 2 months now since I bonded out) and apparently I had court and missed it and have another warrant with a $1500 cash only bond. I don't have that kind of money especially after dishing out $500 two months ago. Is there anything I can do since I was never informed? Just tired of the run around.
