Claims Call Centre line not working.

I have been waiting on feedback with regards to my claim since the end of January<br> I have sent all my documents 3 days after my initial claim yet i was still requested to resend statements just last week<br> My doctors bill is slowly approaching 60 days outstanding after which i will be handed over.<br> So i decided to call the call centre twice today and my call is either being cut or their call centre is unavailable<br> this is unacceptable
