Very Bad Customer service

I lodged the claim with Discovery Insure call center on 18 April (Ref number ***), and an appointment was set for the accident assessment for the following day 19 April at 7:30am. The claim was only approved on 29/04/2016 after almost two weeks. I got an email on 29/04/2016 from the panelbeater which advised a booking was made for the 7th June 2016 which is more than 5 weeks from now. Please note that this car does not have a left mirror, and it is very difficult and dangerous to drive the car without the mirror. This does not only pose a risk to the driver but also to other motorist on the road. There are many panelbeaters around Gauteng. I have phoned the discovery Insure Call center several times to get assistance on getting a sooner date or a different panelbeater that has availability to work on the car, but I'm getting no response. They keep on saying they will phone me back. I have sent email to both Emails *** and *** on 29/04/2016, but I have not received any response from Discovery Insure to-date. It is very disappointing that we as customers have to pay our insurance premiums on time every month, but we are not receiving the efficient service. How is it possible to wait for more than 8 weeks to fix the car( From 18 April to 7th June). This is very inconveniencing me as I'm unable to use my car for everyday use. Discovery Insure claims to be ranked #1 in customer experience‏, but they fail to resolve such a simple query. Very disappointed client.
