Glass Claim NOT paid. Had to repair myself!

I submitted a claim to MiWay's glass claim department. It was authorised and their useless supplier contacted me days afterwards for the installation. A week or so later after multiple follow-ups from my side the supplier came to install the incorrect windscreen. I complained and notified miway. weeks passed and I was still driving with a broken windscreen at a risk. I took matters into my own hands and replaced the glass through a different provider.(This took 2 days). The company I used was very professional and managed to invoice me R800 cheaper than the supplier Miway first appointed. I have been trying to get reimbursed for this nonsense for over a month. I have phoned and emailed countless times. I have complained and expressed my deepest regrets of being with Miway as an insurance company. I do not recommend anyone to use miway as an insurance provider.
