Poor service

I've been trying for almost 2 months to cancel a simple funeral policy. I've emailed the request (took a month to get a reply), and tried contacting them (an exercise in futility). I have even cancelled the debit order - and now they're harassing me about unpaid debit orders! It's not the first time either: cancelling any policy with Old Mutual is virtually impossible. I have also logged a complaint on their website: the response email said a consultant would call me within 24 hours - still waiting! They're ***********, and *********.
