QUICK TO TAKE MONEY - NOT SO QUICK TO RESPOND

I took out a hospital policy that I was uncertain about to begin with through a call centre agent that contacted me on 27 May. I mentioned I needed to confirm with my husband and even said so when they repeatedly ask you to answer yes or no only. I should have said no and be guaranteed I will NEVER offer to further listen to ANY CALL CENTRE CONSULTANT EVER AGAIN! I was told that I can cancel it at any time prior to the first debit order going off which is scheduled to happen on the 15th. After looking at it, it will not benefit me as I would still have to pay upfront which at a private hospital is around 60K and then try to claim back a much lesser amount. I would prefer a proper medical aid. I have tried to contact Clientele but it is 1 computer voice after another never actually speaking to a person. I have emailed, I have left an online enquiry to cancel and on online enquiry for a new policy hoping that at least 1 person will call me. Still nobody. IMAGINE WHEN YOU HAVE TO CLAIM?? Please can somebody call me ASAP to cancel this policy BEFORE the first debit order as per your consultant's advice.
