7 Months Later still no payout

I Submitted a claim last year December its now 7 months of me waiting for a payout, every time I call to enquire I get told about missing documents, I send the docs then call a week later only to be told there is another doc that is needed, I get the doc and send it then its another waiting game, my last call was May and I was told they are assessing the claim and its now over 30 days they are still assessing the claim, very poor service, after paying me I am cancelling the policy, its just not worth the hustle and headache.
