Bad Service

About 4 Months ago I took a policy with Old Mutual, a savings one. Beginning of this month I phoned to cancel it as it was not clear about how much percentage my money will grow and so on i was then told that it can only be cancelled at the Branch not over the phone. I then went to Randburg Square Pretoria Street. When I got there is was told that the system is down and the lady by the name of Xoli let me fill the form and I left my 1 month banking details. 10 Days later when I went to check the progress they told me that nothing was done and I must fill another form, I am not willing to do that i just want my policy cancelled it's fine you take all the money that I have invested but I don't want to see an Old Mutual debit order again. Why is it so difficult to cancel a policy? Why can it not be done over the phone? I am sick and tired of Old Mutual and their *********** staff. I even tried to speak to the Branch Manager, Tumi in Randburg but they are all the same. Can somebody cancel my policy please.
