OLD MUTUAL'S SERVICE IS PATHETIC

I am utterly INFURIATED by the service I am receiving from old mutual.!!!!! I have been battling to get my money back from old mutual. They INCORRECTLY debited me twice for my premium. 2 months ago I logged the query to have the money reversed. Today i am still waiting. I have had to follow up with very little response!!!! THEY HAD NO RIGHT TO TAKE MY MONEY, NOW THEY COULDN'T GIVE A CARE IN THE WORLD TO HAVE IT RIGHTFULLY RETURNED TO ME! In the very minimal response I get from them, I get told that they are working on my query. how long does it take to reverse and return a clients money !!!!!!! it is not your money. I have a budget and expenses I need to see to. RETURN MY MONEY!! I WILL DEFINITELY NOT ADVISE ANYONE TO TAKE OUT ANY POLICIES WITH OLD MUTUAL. THEIR SERVICE IS PATHETIC!!!!!!!!!!
