Awful service, no communication, threatened me

Awful experience; delayed arrival by 3 hours with no communication. Service provider walked straight into my home without introducing himself, greeting me, or apologising for his lateness. He took 5 minutes to evaluate the machine and didn't have the parts to fix it then and there - a gentle reminder that the call out fee is R400 - (it was now 16:00) so arranged to come back the next morning at 9:00. Arrived at 10. Took 10 minutes and demanded payment (over R1300) while the machine was on a cycle. I said he'd be paid when the job was finished - which we argued about what 'finished' looked like - to me, my machine being fixed, to him 10 minutes after he'd arrived. He then threatened to remove the parts from my machine, pushing past me to get to it. I then told him he had two options; be escorted off the property by the armed response or phone his manager so I could explain he'd be paid once I knew the machine had been fixed. Don't bother. Find a company who directly employs its technicians and who invest in customer service. Then please let me know which company it is so I can use them in the future.
