Bad terrible claim service

I logged a claim on the discovery warranty insurance for my car 4 weeks ago. I haven't received any way forward of what is happening with the claim. I've been sent to pillar and post with no direction The warranty claim assessor is very ***********, she doesn't respond to my emails and never calls me to advice what is going on. When I call they always telling me M-insure or whatever they are name is. It's been a month, had I not paid the cost of repair my car would have been at Mercedes till to date. Who was going to pay for the storage? This is very unprofessional from such a reputable company that I trusted. So if I'm in an accident Discovery will take months to repair my car since it's failing to do just one thing. I sent all relevant documents 3 weeks ago. I will be forced to cancel my insurance policy with you. Very unprofessional
