Old mutual group is a ****!

Stay away from old mutual group schemes. I have been investing with them for annuity, I am no longer working and told them to stop debiting my account after several requests I sent them not to. Again I asked them to withdraw as per two pot system, I am not allowed to as my funds are over 15K. Old mutual is a ****, am still in my forties but the problems I am experiencing with them are too much I can't imaging when I'm in my sixtees trying to access my money.
