Extremely poor feedback, no answers_A|_

I had a car accident on Friday 23 Jan, almost 2 weeks ago. My car was booked for assessment last Tuesdsay which was supposed to take 1 to 3 days. I was told that Discovery was still waiting for the assessment report and would receive it at the latest Monday morning, so on Monday I emailed the person doing my claim (no reply), tried to phone Discovery all day (not able to get through). I finally received an email Tuesday morning saying at the latest Tuesday, I followed up without any reply or a message telling me what is going on. I phoned Discovery this morning and explained what my problem was and was told once more that they will let me know, I asked to speak to a manager or supervisor, who was not available and was going to phone me back, since then I have not been able to get through when I phone Discovery or receive replies on my emails. When I accident happened I was so impressed with the service and how they handled it... now I'm extremely disappointed!!! I am self employed and need my vehicle for work... Where am I supposed to get answers? Why do I spend so much money on vehicle insurance every month?
