Disappointed customer

I'm deeply disappointed with old mutual. I have an investment account with old mutual I went to fourways branch 3 times already to withdraw from my investment account, the second time I went to the branch it was on the 26 June and I was told that I will receive the money on after 5 days which it did not happen I went back after. 5 day I was told to wait for Monday 8 July until today. Every time I get an sms that I need to send I'd copy for policy holder I did so only to come to my surprise that I'm not the policy holder but every month old mutual deduct money from my account and I receive statement from this policy I even sent them my son's birth certificate cause I really don't know what to do anymore? I regret that I should have listened to my friend when she told me about this old mutual I'm so disappointed.
