Old Mutual`s STOP Order crumble

I am still not assisted in relation to Old Mutual to just do a simple thing and amend my stop order to the correct amount. This people knows how to bully their clients. I was assured that the issue was resolved and only to find that it was not, which makes me wonder what proof this official was having. Now i am being crusified to pay double. I am soo angry with this kind of unprofessionalism.
