No customer service at Hollard

I have submitted a hospital claim as I have a Hollard Hospital cash policy which I took out 30 years ago. The claim was submitted on 21 October with supporting documents. I received conformation that I will be contacted within 2 business days. The claim was submitted 19 business days ago. I sent follow up email to no avail. I tried to phone to follow up on the number supp**** in the mail, but it is impossible. Nobody is answering the phone. I went through the switch board, I was transferred to the wrong department and then to another department, but the phone just rings or a recorded voice saying "our consultants are currently busy..." for 10 minutes or more. I made 4 calls and all have been unsuccessful. Previously I stayed on the line for 40 minutes with no response. The numbers I phoned were *** and ***. Hollard just has NO customer service. I can't even say it is bad, it just doesn't exist. I am very worried as I have other policies as well as life insurance policies with them also.
