I canceled my contract last May but I have still receive your invoices in June and July.
How can I make sure that my contract is terminated? Do I have to pay another bill?
I already moved to another country and I can't speak Dutch.
Thank you for your help.

These are the chats that I did last May.

Liz (2021. 5. 21. 오후 4:06:48): I see your contract is actually till 17/09/2022. I can cancel it earliest on 21/06 because of the month notice time. Because you cancel it earlier then it ends there will be a disconnection fee. 
Ik (2021. 5. 21. 오후 4:07:48): If I canel it on 21/06, there will be no disconnection fee? 
Liz (2021. 5. 21. 오후 4:08:16): Yes there will be, because it actually end on 17/09/2022

Ik (2021. 5. 21. 오후 4:11:10): It is quite a lot for me to pay...... 
Ik (2021. 5. 21. 오후 4:11:57): Is there any other way to make it less? 
Liz (2021. 5. 21. 오후 4:13:28): No unfortunately not. An other idea if you are not using it, is changing it to the lowest abonnement.

Gul (2021. 5. 22. 오후 2:24:42): Your subscription will end on the 21st of June. Your invoice has been paid untill the 17th of June, so that means that besides the payment you made of 123,02, you need to pay for 4 more days for the subscription. 
Ik (2021. 5. 22. 오후 2:25:06): What do you mean? 
Gul (2021. 5. 22. 오후 2:25:54): You made a payment for the disconnection fee of 123,02. 
Gul (2021. 5. 22. 오후 2:26:48): Bu besides that you still need to pay for the monthly bundle for a few more days, because your subscription ends on the 21st and not on the 17th. Your current invoice is untill the 17th of June. 
Ik (2021. 5. 22. 오후 2:27:21): Okay. So do I need to pay more? 
Gul (2021. 5. 22. 오후 2:27:26): Yes. 
Ik (2021. 5. 22. 오후 2:27:33): How much is it? 
Ik (2021. 5. 22. 오후 2:27:55): I will close my dutch account soon bc I leave Netherlands tomorrow 
Gul (2021. 5. 22. 오후 2:28:27): It's like €3,- 
Ik (2021. 5. 22. 오후 2:29:09): If I pay that, then there is no more payments for me. right? 
Gul (2021. 5. 22. 오후 2:29:16): Exactly! 
Ik (2021. 5. 22. 오후 2:29:50): Great. Can I know the exact amount of money and bank account? 
Ik (2021. 5. 22. 오후 2:30:52): And I want to know whether my contract will be finished automatically after I paid everything. 
Ik (2021. 5. 22. 오후 2:31:05): Is there smth I need to do after this? 
Gul (2021. 5. 22. 오후 2:31:20): Yes, on the 21st of June your contract will be closed automatically. 
Gul (2021. 5. 22. 오후 2:32:09): The exact amount for your end invoice i don't know. I know it will not be more than €3,-. It's like €2,77.
