Horrific Service Provider and Insurer

Would love to give negative review but not possible. Discovery sent service provider to fix my alarm that was hit by lightning in October. We now end of January and alarm still not completely fixed. I have sent daily emails but to no avail. Service provider charged Discovery for items that they never replaced. When I ask them to supply and I will arrange new installer I am ignored. So many issues with Insure please avoid them. Emails have automated response we will get back to you in ***x hours. It's been weeks and nothing
