Submitted a claim regarding my Tablet

I submitted a claim for a damaged Samsung Tablet on 24/06/2015 and they responded with banking details and amount to be paid in October after I called several times. They came to collect only in Mid November and kept my tablet with them for 3 months without any communication from them. They returned it today, screen blank, tablet not switching on and not charging. I have been experiencing nothing but bad service from this insurance and am fed up. No communication, misinformed staff and not proffessional at all they do not value their customers
