Bad service from Hollard

I am giving up. I have called Hollard so many times about hospital cash back plan that I took out a over a year ago. I have submitted a claim on 7th June 2018 for 7 days that is was hospitalised. Every time call in the call centre says the claim is being assessed. I can't speak to claim department because they don't have a number for them .I have numerous reference numbers .No one from claims department is calling me back. Reference numbers ********** ********** 627 ********** 639 ********** 642 ********** 648674 and so it goes on and on. Surely for a company as big as Hollard it should give a bigger service than this .I pay my premiums every month but when it comes out for a claim they take so long I would really like someone higher than call centre to look into this My policy nr is ********** 2
