Bad feedback

Good day

I would like to complain with regards to the lack of feedback from miway about my complaint I lodged to do with my lights tripping. They sent an electrician out who checked my DB board and all my switches, he then confirmed that it was my stove that was faulty, even though we don't have the stove on in the mornings, so for me this was weird. They then said a company called Black Legend would come out and assess my stove to see either if it would be fixed or replaced. This electrician came out and did the same and said it was the stove, however when they reported back to miway they said it must be DB board. They didn't open the stove at the back to see what the fault is or even check the connection in the wall, they took pictures of the stove and confirmed that its not damaged. Well its obviously not damaged as it was not pulled down the freeway, there is an electrical fault. They then send the first guy out again who says he doesn't know why he was sent out because he told them what the fault is. In the mean time now this is coming out of my callouts for the year. Instead of miway sending out an electrician that is an all rounder and that is going to do a complete check of wiring and everything to ensure that this problem is resolved, they just keep sending people up and down. So now I have heard no further feedback and my lights are still tripping, so maybe they are waiting for something more serious to happen. I am very upset about this and now my callouts have been wasted on people who have not resolved the problem.
