False Information Given about Timelines

My father had life insurance, pension fund and a funeral policy through Old Mutual Superfund as a benefit from his employer. The funeral benefit took 2 months to pay out. The other funds are still outstanding due to verification. They have paid out a funeral benefit but need to verify if the person is truly deceased? Their website states the following: "The standard timeline we communicate to customers is 15 working days. Generally most claims take far less time to process. This is to manage expectations as various scenarios could cause delays in processing and payment. Depending on the claim, it can also take up to 60 days also depending on requirements." We are much more than 60 days past submission and there is simply zero communication or progress.
