I was asked to do a move out clean, I have my one cleaning co and work as a sole proprietor so I cleaned this house it’s was beyond disgusting, I took tons of pics as always showing client that work was being down and showing the process the entire time sent the professional invoice as alaways as to what was down etc and payment due immediately after services are rendered.. she refuses to pay me and has said she will call police for harassment? What should I do!?
