Worst Service experience ever, totally and utterly useless Company

I have been trying to get a hold of Hollard for close to 2 months now, it is in regards to a claim I'm trying to do on my late fathers Edgars account, the policy is underwritten by Hollard, so, unfortunately, I have to try and deal with possibly the most useless company I have ever had to deal with before when you try and call any of the numbers associated to Hollard, it just rings and rings non stop, all you get is the usual automated voice message, ''Your call is important to us, please remain on the line and one of our consultants will be with you shortly'' literally no one answers the call, have been going through this for as stated nearly 2 months now, also have tried emailing various departments, again automated responses with we endeavour to reply to all queries within 5 - 8 working days, again nothing ever happens, have posted complaints on social media, again no response, what is one to do, to actually get hold of Hollard? the stress and trauma of losing a loved one is bad enough, having to deal with total pathetic useless service from a top-rated company is only adding to that pain, as all we want to do is get some assistance, not have to continuously struggle to get ahold of someone, I honestly do not know what else to do to get a response from someone from Hollard directly. maybe I need to consult the ombudsman, or make an even louder noise on social media, or better yet get hold of the local press and sing so loudly about how utterly useless Hollard are,
