Fix you processes and look after your clients.

your plumber installs a faulty geyser and I have to wait 5 days to get hot water because it now had to be a warranty claim to the manufacturer.

I'll cancel my policy and go somewhere else, I'll go and get my own geyser and you can come and fetch your geyser off of my pavement. you need to look at your processes. Why must i be at the end of these technicalities. If a plumber installs a geyser and it doesn't work then they can take it out back to their premises and the manufacturer can come and sort it out there premises
