Bad quality work, incompleted work

I had Werner Joubert from The Chilling Effect to do electric work for me. He quoted me and I paid 60% deposit. He started with work but only completed approx 40% of the work and also on extremely poor quality.

I asked him to rectify and complete his work. He refused. He started to intimidate me (a woman). The more I told him to finish his work he will get paid the more he continued to intimidate me.

I asked him to produce his licenses, and he refused.

His intimidating behavior towards me continued.

I would not recommend him.
