OLD MUTUAL - Invest your money and lose it

Requested to cancel my savings investment. After a month or two it was eventually done. I log into my OM account and over R7000 is gone out of my savings. Old Mutual has not bothered to notify me via email or call as to where this money is. The irony in their lack of response or interest is that I received exceptional service from one of their staff members, Shaudiqan Adams, unfortunately she cannot assist me with the pay out. How do you manage people's money and have over 7k just disappear?? I have called the lady numerous times that is meant to give me feedback, yet she is never available. I have left a message for her and it has not been almost 3 weeks since a gentleman named Blandly told me someone would be in contact with me to explain what happened. Well done Old Mutual - You have just lost a client and basically made my money disappear into thin air without the decency of an email or phone call.
