Extremely poor service for a claim logged more than 6 months ago

We had an incident with our vehicle on 8 Dec 2017. The front of the vehicle had caught on fire. This was communicated to MiWay and they had the vehicle towed away. When advised the amount I would be paid out after excess was deducted, I opted to repair the damaged vehicle ourselves . (Vehicle was fixable but MiWay opted to write off stating that it was uneconomical to repair). I had to constantly contact MiWay via phone and e-mails. In most instances I could not get through to the relevant person via phone. On one of my calls I raised a concern regarding theft of vehicle parts while it stands at their appointed area and was assured that the vehicle would be returned to me in the same condition it was after the accident. On receipt of the vehicle, this was not the case. There was no major damage but parts theft and small incidents which would be additional expenses on our side. I immediately communicated this to MiWay via e-mail and with supporting photos. As in most instances, my e-mails received no response. I have even asked to speak to the manager to no avail. On 16 Mar 2018 I received an e-mail from MiWay after further e-mails and calls and logging 2 call back requests on their websites. Even then I was not transferred to someone who could assist me with the claim. I held on in excess of 12 minutes for the 1st call, then cut the call and on the 2nd call, after 10 minutes I was advised that someone is currently working on the claim, but call could not be transferred to them. The e-mail comprised of a letter which I am required to sign regarding the amount that they are paying out in settlement for the claim. No mention was made of the issues that I had previously raised or the delayed response time. This entire issue with MiWay is without doubt the worse “service provider” experience that I have ever had. Last e-mail forwarded 8 June 2018 and still no response. I have since tried calling and no one answers, it goes straight to voice mail.
