Hi, we gave notification via email THREE MONTHS in advance that we wanted to cancel the contract for Festnetz because we are leaving Berlin, and you confirmed on the phone that our last day of the contract was 30th of September. Now I receive a kündigung letter saying that you will cancel on October 31, and that I need to pay one more month even if I am already NOT LIVING IN BERLIN. I need an URGENT letter confirming that my last day of contract is September 30th, as you told me on the phone, because that is my last day in Berlin and because I already gave THREE months in advance notice. I need an URGENT ANSWER.
