Bad experience

I have been sent from pillar to post by the old mutual trying to get them to cancel a stop order against my salary which they executed without my consent, when i signed my 3 policies with their representative she told me that someone from their call center will call me to get my banking details and arrange a debit date, the call never came so i called the call center and only then was i told that there is a stop order in place, i asked them to cancel it and i was told they can not do that i must cancel it myself with my payroll, my payroll says they don't do administrative work for old mutual and old mutual needs to exclude e from the stop order file they send to my work, i called the call center yet again to advise of that and i was told it can not be done all they can do is send me a cancellation letter i took the letter to my work and still they wont cancel as it is not their duty, um at my wits end i dont know how to get this issue resolved i am really irritated that they have a call center in place that is totally inexperienced to deal with anything at all really, i now have to their job trying to get this mess resolve this mess Thulile created by being dishonest with me......
