By signing for automatic withdrawal I authorize Aktief Slip for the automatic withdrawal of €10,00 from my transfer/bank account as payment of my membership. Payment will take place once every academic year. If I want to withdraw from my membership, I will send a written notice (a letter or an email) to Aktief Slip before 1st September of the year. If I send the written notice later, I have automatically renewed my Aktief Slip membership for the next academic year and I am obliged to pay €10,00 for that year of membership.
