I am not happy about the claim service of Old mutual

I am not happy about the claim service of Old mutual. 3 weeks back I submitted a death claim for my late cousin and I submitted the required affidavits to confirm relationship and even gave them the contact number of the deceased`s mother to verify the relationship. Until now they are still verifying the information and have not received feedback. The funeral has passed and I had to make other alternatives to ensure that the burial takes places and Old mutual is still playing hard and seek with my claim. The company has failed me as their client and I am very disappointed in their service.
