Terrible service. Old Mutual

My husband past away last year Jan he had some policys with old Mutual since last year I've been try to get them to pay out. I went to there offices in Festival mall and asked them to help me to make sure that al the right documents were there. Then I received a call some more documents is needed I went to hand it in. SMS to say with in 10days. Nothing happened I went back to the office. Yhay can't see anything wrong. My claim het escalate nothing happened. I phoned them and again they need more documents. I send it to them and nothing happen. I send a complaint to there complaints department and they say 10 working day. Just after new year a small amount get paid out and since then the lady of the claims department is ignoring my emails. They are happy to take people's money but can't pay them out when needed.
