How to cancel Netcologne by mail
Collect the details you need
Start with the account number, the phone number or service address being cancelled and the name on the account, so the request to Netcologne names the right account the first time.
Set out the request
The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post the letter
Send the letter to the Köln mailing address shown below by certified mail. Keep the tracking number safe.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Netcologne was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Netcologne cancellation letter goes
Netcologne lists Am Coloneum 9, 50829 Köln, Germany as its mailing address.
Copy the postal code 50829 exactly: it is what routes the letter to Nordrhein-Westfalen, Germany.
The letter greets the reader with “Sehr geehrte Damen und Herren,”; your own details sit under the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
