This is a classic defmation case with defamation "per se". The issue is really are you inclined to spend several thousand dollars on legal fees filing a lawsuit over such an issue for damages. If not, you rub dirt on it and move on. Otherwise this will escalate an you will end up spending even more money to address it later or worse have no ability to do so and still have a worse issue.
