My telephone bill waiting for answer is same as pensions funds due to me

I have been holding on to try and talk to someone about unclaimed funds in your Superfund. I received a 'noreply' email stating that my query had been received. When I tried to talk to someone on the phone number given I held on for 30 minutes !! As a Government pensioner I cannot spend all the Unclaimed Funds on a telephone call to Old Mutual. I am claiming the funds on behalf of my deceased brother and need to know what steps need to be taken in order to do this. Can a real human person please contact me to answer my query. Thank you.
