Unprofessional and ******** hold a my money.

I was a customer at standard bank Phoenix ,when my account was frozen with no explanation. This happened almost 2and a half years ago. I've been going to the Phoenix branch asking the manager for help but he says there's nothing he can do. Even sent a mail to the ombudsman, they said I should allow them Time to investigate the matter. 'but come on guys' it's been almost 2and half years. I then went to the yesterday and the floor manager at Phoenix bank helped me to find out what's going on. He said that there was no notes or investigation done. Can anyone tell me is the bank allowed to do this.? I jst want them to give me back my money in my Account.
