Bad service Old Mutual - No responses on their own site

My husband passed and has two policies with Old Mutual. I used their web-page to find contact information to sent through claim documents. I tried calling as I wanted to know which claim form to use. Two weeks ago I submitted a complaint on their website that says they will sent you a copy of your complaint. Nothing happened. Last week I went through the same process, nothing happened. It is impossible to find anyone to assist or contact. The claims department that received the documents can not be reached. Emails are not answered.
