I'm a Hunter Douglas window fashion representative. I've installed the 16 shades that were custom ordered and customer refused to pay balance at time of installation. She contacted me a week later complaining shades where fraying on some of custom shade edges. I worked with Holli Gabler for 4 months to offer her replacement solutions at no additional cost to her. She still has refused to pay and after placing lean she has emailed me saying she "I should have let it go and now she will sue me to remove the lien". What should I do at this point?
