Cellphone claim ignored for Three weeks no feedback from insurance

I have lost my phone and reported it 3weeks back untill today no response from the company everytime I call to enquire Im told to forward my claim documents or they are still waiting waiting for people who are dealing with the claims that moment I have submitted a with my own email second incredible connection email third instructed to forward that claim application and still nothing all that done weekly . I took out this insurance for a good reason of the kind of work I do but now I find myself frustrated and stress by this whole thing. I can't work or manage my business without a cellphone.
