Aggressive Unprofessional Technicians

I phoned and asked someone to come out to quote me on the installation of a secondary WiFi point. Two technicians arrived at 16:50 told me that they will need a lot of cabling and that it will take four hours to complete the work. I said that will meen that they will have to work until 9pm. They said it’s no problem to which I rep**** I have a problem with that, we can’t be drilling and making a noise in our complex and my daughter had to study and go to bed by 8pm. They then said it will be R5500 to which I immediately rep**** that I can’t afford that and that it’s seems very expensive. The one guy aggressively rep**** that I must then pay a R350 callout fee…. I said why didn’t you inform me if this when I phoned. He then said he’s going nowhere until I pay him….I had to phone the security and police to get rid off him. So unprofessional, aggressive and unacceptable.
