Premium Hospital Cash Back

I took out 3 Policies on 24 April 2015. On the 21st of May I sent emails cancelling the policies. One of the policies was cancelled and I was promised to have money returned for this policy. The other two policies were not cancelled. At the end of May money was deducted for these two policies. I sent another email on the 2nd of June to ask what was happening but no response. I was under the impression that the policies were cancelled but have not had any money refunded. My bank has just informed me that ANOTHER debit order has gone through my account deducting for the two \cancelled"policies. I have all the emails to prove that I have cancelled as well as confirmation emails from Clientele that they have received my emails. Mpho helped me today and asked me if I have sent a SIGNED letter through to them to cancel these policies! And I get told I am going to lose my money! One policy cancelled without a signed letter and two other NOT cancelled but NOW I need to send a signed letter!! I WANT MY POLICIES CANCELLED AND RETURN MY MONEY! I had to spend 25 mins on the phone explaining 3 times including re-sending emails! """
