Ghastly, shameful service

What absolutely shameful and disgraceful service. Came to fix gate. Apparently needed new motor. I wanted sensors. Installed motor. Wrongly placed so doesn't engage every time I have to change from manual to automatic after loadshedding. Motor inadequately secured, so moves around. Told me motor wouldn't work with sensor. Told them I wanted refund. Suddenly no longer a problem - installed! Several phone calls with promises of attending to problem. Patently dishonest.
