I'm Very disappointed with MiWay

I have household contents policy with MiWay, it occured that my fridge stopped working suddenly. We called in a technician to take a look at it, and he gave us a report and quote to fix it. We then thought, why not claim from insurance since we have a policy to cover for such events. We claimed from MiWay, they later sent their assessor to come have a look at the fridge, he didn't do much he just looked and then wrote his report. Later MiWay came back and said the assesosor found that the fridge is not working due to power surge (loadsheddings as a cause) and the claim is approved, they won't be able to fix it, they will buy us a new one, I was like 'nice', they unfortunately said that I need to pay R4.5k of excess, and the fridge price is +R6k. I was disappointed, we then decided to fix the fridge ourselves, and the fridge is fixed and working just fine and the cause wasn't the power surge. I later sent them a complaint about the assessor's report that was saying the opposite of what our technician said in his report. I mentioned that MiWay sends us dubious or *****ed assessors, because as I was watching how he did his assessment, to me it looked he had already predetermined his report before he came. because he didn't take out his tools to check thoroughly what the problem was. They then responded to the complaint and they said they'd do an investigation as to why the assessor's report is contradicting our technician's. It's been a month now since Aug 11th and I am still awaiting the investigation report. MiWay is very quick with services of that I know for sure, but this time it looks like they were caught with their pants down. I think I will cancel the policy.
