OLD MUTUAL WON'T LET YOU GO, EVER!!

I have been trying to cancel my education plan policy with old mutual for 2 months now. All documents requested from them were sent through, and a month later the premium was deducted again. When contacted they claimed that there were now more documents they needed me to complete, but they just didn't let me know. That was done and sent through. A month later (and still no money paid out) another premium was deducted. They actually had the nerve to tell me to go to the bank and stop it myself, which I can't because it is a debit order not a stop order. I have phoned them countless times, every time a new call center agent has to go through the whole story!! One time they actually told me there was nothing on the system for a cancellation, until I gave them the reference number then they could all of a sudden see it. There is no way to get my money back. They simply keep it and they can't even come up with proper excuses, they keep saying they don't understand it either.... I mean really!! STAY AWAY FROM OLD MUTUAL. Once you have a policy, it is for life, they won't let you go.
