If you contradict a SEPA direct debit, this means that you have not paid your contribution. A chargeback of the direct debit can also cause us costs, which we may charge you. 
In addition, your insurance cover may be jeopardized. 
Please note: You have a daily right of cancellation, so if you do not want to  be our customer anymore, you can save your and our time and money by canceling instead of simply getting your premium refunded.
