Accident claim

I have submitted a claim last year in November which was approved, however there was parts not included/ omitted for my repair, on my review I requested that this be looked into and it took well over four months to get a response. Finally they agreed to amend and add the omitted items but two months later going onto three they refused to update their documents and send me a form to allocate payment. It’s so frustrating and disappointing knowing I’ve been a client for 3 year and this is my first claim. You think an insurance company would be there in time of need well that’s definitely not Miway. If you are a client and if you thinking of becoming one Don’t waste your time or money.
