What happens if I got my dates mixed up and I miss my court hearing? Who do I contact in Flint michigan

Which court? If not in big courthouse go to the counter at the McCree bldg. They should be able to help

Depends. If a default was entered for non appearance, you must file a motion to set aside default. Clerks can give forms but not legal advice and won't help you complete the form either. Then you go to the judge and explain. If you have good cause, he can set aside the default; if not, such as negligence, you just lose.(this is my opinion based on experience and is not legal advice.)

Contact the Genesee County Jail. They’ll know what to do with you.

In the same position the cop told me the 20th of this month nope it was the 16th but it's only a traffic ticket would I still have a warrant?

You well have a warrant so go in front of the judge maybe well cancel it and re schedule it.
