Ding Dong Plumbers - Germiston

I had a very bad experience with the plumber. Him and 2 guys came out to carry work of unblocking my drains at my unit. The 3 of them walk into my house, through to my bedroom without requesting me to escort them. When I asked them how they can just walk into my bedroom without me escorting them, then the one guy yelled at me saying " you think we are thiefs? This is not your own house, you are renting.. Most customers leave us with their keys, who do you think you are". I felt violated and disrespected at my own home. I was a woman and had 3 Strange men at my home who were supposed to provide a service, instead I felt vulnerable and disrespected.
