How to cancel Unitymedia by mail
Find your account details
Before writing, collect the account number, the phone number or service address being cancelled and the name on the account. Unitymedia can only act on a request it can match to an account.
Draft the request
Because Unitymedia is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail the letter with a receipt
Use certified mail for the 40549 Düsseldorf address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Unitymedia 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.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
