bad service

I took an Old Mutual policy in 2013 from Wilfred who seemed very professional at first and would assist me everywhere possible regarding my policy.The problem I have since the commencement of my policy is the deduction method.I requested to have the deduction to be made ythrough my persal instead of my bank. He promised me that he will assist me with it, but since February of this year he has been ignoring my phone calls and I am not happy with that because the problem persists.
