Powerflow Midrand - Useless!

I took my Polo GTI to fit a downpipe at the Powerflow in Midrand a few months back.<br> They did not put back half the brackets, which btw I had to replace myself. Besides that, they cross threaded my O2 sensor and broke it, they than patched it up with fire gum, like seriously who does that??? But what really ****ed me off is that they dropped a exhaust nut in between the radiator and ***ling and left it there which resulted in my radiator leaking. This cost me in total 5k for the radiator to be replaced, another 2k for a second hand O2 sensor (as a brand new one was 4.9k from the agents). These people should just close down. Rather go to the Powerflow in Edenvale or Randburg, they know what they doing and offer a great service. The Midrand branch is a bunch of kids who really need to take a lesson in cars. My experience was a very costly lesson.
