boss threatened me and I have no idea why

This morning my boss pulled me over and basically said someone complained about having to tell me multiple times to go back over my work or have someone else do it…I do my job very well and was never ever told to go back over my work by anyone and pretty much threatened to put on a shit crew doing even shittier jobs like wtf it's bad enough I'm severely underpaid but now he's making shit up..as soon as I get my licenses and wheels I'm out of this shit show
