Bad service

I'm insured with miway since Nov 2015, on Saturday 09/09/17 I was involved in a car accident. I was overtaking this other vehicle which was slow moving in the front, while I was overtaking the other car sideswipe mine on the leftern side my car was only dent & scratched. +/- 100 meter away the other car overturned, I made a claim with miway on Monday 11/09/17 they did their investigation/assessment but still now there's no final report regarding validation or not. since last thursday I've been contacting them and they are sending me from pillar to post they have failed to pull-out the tracker report which will indicate on how fast I was driving? They are basing the report on the partys statements of which I believe it's baseless & not valid. Making matter worse they claim they interviewed other people about my driving & life style behavior, of which it's known that other people don't others. Out of all this still they don't give me feedback. Really dnt know what are they looking for now, I've been paying R1088 for a 2006 BMW 320d.
