How to cancel Hilfswerk Kärnten by mail
Start with your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Hilfswerk Kärnten holds, so the request can be matched to your account.
Draft the request
Postbye writes the letter in German from our German template, because Hilfswerk Kärnten's address is in Austria. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Hilfswerk Kärnten to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 9073 Klagenfurt. Keep the tracking number it gives you.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Hilfswerk Kärnten 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.
