Hartland cleaning Wont pay me for hours worked. Lincoln Nebraska

I worked for this company for 4 months I decided to put in my notice the last two weeks they made my life a living hell they told me that I was ripping them off on the hours that I worked and they were talking off some hours. But he first three and a half months were just fine they had no problem whatsoever of paying me what I wrote down. the last two weeks they're telling me that my hours didn't match what I was working. These people are a bunch of backstabbing cunts. I strongly advise you not to do business with them whatsoever!!
