Hi @HristoHT, this is good question. Thanks for asking! I will tell you all about it. Your discount included monthly discounts for 8 months. As your subscription started in February, you have entered the last month and there was a small amount of discount left to credit. In the new coming invoice, all the discounts will drop and you will pay the full amount. 

Please note that you are not enjoying Klantvoordeel discount. You can arrange this is Mijn Odido and connect yourself to the Klantvoordeel discount! Do you want all new discount? If you are a happy customer, you can renew your contract with us with all new discounts. You can contact 0800-0092 if you want, as I can't discuss it here.
