I was dismissed of all criminal charges (factual innocence and insufficient evidence, it was a misunderstanding essentially) and now I'm getting a civil demand of $500. I told them I was dismissed of all charges and I won't be paying anything because there were no damages and no merchandise taken. Now they're threatening me and trying to extort the money out of me by saying they're going to ruin my credit and take me court and sue me and all this crap. I was forced to sign a paper saying I wouldn't visit the store for 90 days, but I signed those papers under duress and to my knowledge, I didn't sign anything admitting guilt.
Can they re-file criminal charges and drag this on? What should I do?
