Nightmare to claim from Edgars/Hollard Funeral Cover

My Dad took a funeral cover with Hollard via Edgar's. My dad passed away in January 2021 and I am trying to process the claim however this a nightmare. I have been calling the numbers given but cannot get through to a consultant. I have email them the required documents but all I get is the follow up emails advising they will contact me or I should call a certain number ..... every number I call says the same thing "thank you for holding our agents are busy ... Or Please stay on the line we will be with to you shortly..." I have also tried submitting via their wats app service also a waste of time. they did send an sms on my dads cell advising I need to fill in a funeral claim form, My question is how to I get the correct form to full in when I cant get hold of them. Such poor customer service. I will never advise anyone to take a cover or any policy with Hollard.
