Pathetic service from FOGI and Starplex maintenance

Please don’t send out extremely useless plumbers (Starplex Maintenance, Centurion) to my home to sort out issues. They don’t show you the issue and what they repaired, I must just take their word and complete a competence form when I had no clue at all what they done. They guy was literally 10 minutes here and replaced a elbow joint. Insurance is to pay the first hour yet M Klashorst is charging me R1850? For what?
