Poor returns, high costs & Pathetic customer service

Don't invest them they have the lowest return and highest costs and worst of all pathetic customer service. I requested a cancelation of an investment policy. An agent replies requesting that I send a signed dated letter which I did. I followed up each week with no reply. They reply over months later requesting with forms etc to fill. Why could they do that in the first place. It's time wasting so they can earn most exbortant costs on my money
