Your business partners are terrible

I called yesterday to check in on an error. After going through a few processes I was advised that there was a technical error on my connection. I was given the number of a company and told that I would not be asked to pay more than about R200. I called. The company arrived and advised that the cost of the repair was R800, AND that I would be charged a call out fee of R400. when I complained the technician became very aggressive an swore at at me while on the phone. Afraid, as my Mom was home alone, I just paid. This is totally unacceptable and I am disgusted at the general service from start to finish!!!!
