Beware of Old Mutual!!!

I am a pensioner that changed my bank account details. Old Mutual paid an amount into my bank account from an investment I made with them . It has been 3 months and they are still paying it into the wrong account. I have contacted there complaints department and the only answer I get is that they can’t find my details. They have an automated phone system one is sent to one department to the other The worst Company to invest your money because you will not see it again !!!!!
