Investment money

My mom wanted to make an investment with old mutual, they told her that they will debit from her account then she should come back for paperwork, when she went there on the 16th of November a large amount was debited for the financial advisor that she didn't ask for, she then told them that she is withdrawing, doesn't want the investment anymore, that guy told him that money will be reversed in 48hours which didn't happen, she went back to Old mutual after a few days, when they checked money was not reversed and they did the process of reversal and she was told that her money will be reversed in 15 working days, after more than those days that we stipulated still no money, she went to Old mutual on the 2nd of January, she is sent from pillar to post for her money, I'm not happy because my mom has heart problems and now she doesn't sleep at night because of Old mutual Eyethu mall, Orange farm
