Emergency Appliance Repairs - Complete Ripoff

A team of 3 came to fix my bosch dischwasher which had an error where the tap light would flash. As I was not home they phoned me to say the capacitor had blown and the replacement would cost R950 for the part, R450 for labour and R200 callout fee. I agreed, they did the replacement and the dishwasher now works. When I got home I tested the ''Blown capacitor'' with my fluke multimeter and found it to be in perfect condition. I tried to call the owner as well as the technicians for an explaination but they dont answer. Besides the fact that they didnt have to replace the capacitor, I also phoned around and got a quote for R231 for a new capacitor (I was charged R950).
