Disgusting slow response of handling claim submission and appointing companies that cant do the work timeously

I submitted a claim and sent photos of damages after lightning bolt shattered windows in house, knocked out all electricity and tree fell over which landed on top of our roof damaging structure. Luckily our security company assisted with covering hole in roof with a ground cover as the rain water was flooding the house. Discovery appointed an assessor who sent through the report and I received a mail requesting me to sign off a settlement amount. I requested details of what the settlement covers and what work they approved. Now the roof company appointed are unable to assist urgently to prevent further damage to the house and have asked Discovery to appoint a new company. We are sitting with no lights, no alarm, no security a few plugs, no oven, broken TV and lots of other appliances broken. I have emailed the Discovery staff member handling the claim but the urgency of his response is shocking. It is 3 weeks now and the only thing fixed is we have the circuit breakers replaced giving power back into the house. Please can someone hurry this claim and get the work done before the people go on vacation!
