Money mongers

Would have giving zero stars. Had the company come to do a water coc. They said I need 6 angle valves, but only needed 4.They quoted R3900 to supply and fit 6 which cost R100 each and 10 min to replace. They quoted R395 for a nut of one of taps to be tightened. Apparently 2 mixer tap handles were broken which it was not and they quoted R650. Also angles valves is not required for coc. These people don't know what they doing and are money mongers
