Poor service

I have had the worst experience with retirement fund,ever since the withdrawal started they are unreasonable..we understand the volumes of application that they may have received but there is no update at all ,when you phone their offices the line just drop ..I hope there is a way one can move to another retirement fund otherwise I am very disappointed by their service. The time frame the gave for the pension to be paid out has long gone and still there is no update on what is going on.
