Discovery/Disgusting Insure

I have been received the worst service from claims administrator who has failed to communicate all/any vital information regarding my claim. I have called their contact centre various times 20 times or even more. I have escalated to two team leaders but still nothing no joy. Discovery is quick to take my hard earned money every month without fail but the drag their legs when coming to claiming since they are in the business of taking their customer for a ride. Friday is promise day you will be promised & disappointed every Friday.
