insufficient information and invalid deductions

I took a funeral policy with Clientelle Life but cancelled in the cool off period due to financial reasons. I cancelled on the 12th of March 2015. <br> <br> A attempt to deduct a premium was made on the 20th although o arranged the debit only for the 25th - when I know for sure that there will be money in my account. <br> <br> The premium was again deducted on the 25th. <br> <br> It was never explained that it is after the cut off date concerning a debit order cancellation. <br> <br> This is now firstly impacting my bank record and secondly my other debits as money that I did not plan for nor have the funds have been taken from my account. <br> <br> This is unacceptable.
