Policy NOT cancelled after calling call centre

I have taken out a policy with Regent and I was told that I have 30 days cooling period to cancel the policy and get my money back that has been debited from my bank account (conversation took place on 23/06/2015). I phoned Regent before 21/07/2015 (if the specific date is needed I will get a itemized bill from cellphone company) to inform that I am enforcing my 30 day cooling period for this policy and that I am cancelling my policy with immediate effect and that I also would like my premium be paid back. Call centre agent that assisted me said that she will send through the cancellation. <br> <br> I waited patiently but now I am no longer waiting for any premiums or anything as I just received a notification from my Bank that ANOTHER DEBIT ORDER from REGENT INSURANCE was presented AFTER I CANCELLED my policy! I have NOT gotten ANY MONEY BACK from my COOLING OFF PERIOD and now they are debiting again! <br> <br> How can I say to anyone that Regent is a good company? If this is how my instructions was processed how would they have handled my claims???<br> <br> Regent Insurance Company, I want answers to how this happened and what you are going to do to rectify this mistake from your side.
