Shocking service and attitude!

This contractor did some electrical work on my property two months ago. He replaced light fittings of which the one was hanging by a thread, I sent him pictures to show him the fitting was hanging, he said its not an issue just need to be pushed back up. 3 weeks later and I'm still waiting for this to be resolved, no follow-up since then. I had plug points replaced and bits and pieces done by this contractor which is now very concerning. My next stop will be calling the call center for Independent contractors and also contacting the electrical conformance board and sending them the pictures of the work that has been done.
