Hi,
It has been 3 months since I terminated my internet subscription, you are still sending invoices! I delivered the modem to you, I received a cancellation confirmation e-mail from you, there are screenshots below. Why is the invoice still being sent? It has been 3 months since I left Germany, closed my bank account, moved abroad. What invoice is this?
