The most useless insurance company I have ever had to deal with

I have had an absolutely terrible experience with Miway Insurance. A Miway customer drove into my vehicle in the last week of March this year. I submitted the required documents to Miway's 3rd party claim department 2 days later and got confirmation that the documents had been received and my claim was being assessed on the 27th of March. As of the 15th of September, I have still not had my car repaired or even been contacted by Miway to let me know if my claim has been accepted or not. I am theoretically still in the assessment phase 6 months later. I have sent multiple emails and phoned a few times as well. The Miway client who caused the accident has also contacted them to complain about the lack of progress, and all I have received are vague responses, such as "my manager will look into it". I used to be a Miway customer years ago and this has been a vivid reminder as to why I left them. I will now have to waste more of my time in taking this complaint to the insurance ombudsman.
