EXTREMELY LONG CLAIM PROCESS

It has been almost a month since I logged my claim with Discovery for my car. Since they have taken the car in, communication on the progress of my claim has been terrible. First of all, it case has been moving from person to person and all I get is an sms to indicate this without further details on the stages of the claim. Last week I received communication that my car was written off and I had to provided the relevant details to the Claims Administrator Kayleigh. I responded to the given email address and no response was received until I had to follow up. Only to find that she had given me the incorrect email address and therefore had not received my documents. I have since resent the email with assurance that action will done on my claim. But still no communication from them. When I try to call i have to wait for at least 30min before I can reach anyone at the claims department - this is absolutely ridiculous. The car hired for me by Discovery is due back in four days time as they say, yet they cant finalise on my claim so that I can get myself a new car. Now I will be left carless - while I am paying an uninterrupted premium!!! DISCOVERY YOU REALLY NEED TO DO BETTER!!!!!
