"Customer provided broken/old light switch for installation. Bought rebuild kits because they were “cheaper” even after they were told we do not install rebuild kits due to our company insurance policy. Performed shower bar installation and placed where customer requested and was told and showed would not be level due to location of bar. Performed sink repairs, after the sink repairs were complete and sealed customer had us uninstall sinks and had us clean surrounding area due to customer’s neglect to do prior to install. Scheduling conflicts were due to customer having surgery and medical appointments during opening in company schedule then demanded that we cancel on other customers to accommodate him. When technicians and owner showed up to the job to finish requested work customer started screaming and cursing at said individuals and demanded refund and work be completed for free."
