The addresses we hold
One place for Sonne International's mailing addresses: the Vienna delivery point for a cancellation letter first, then the rest of what the database holds, with envelope wording that matches.
Where the letter goesMailing address

How to address the envelope
Use the address letter for letter
Address the envelope to Franzosengraben 2/EG/04, SONNE – International, 1030 Vienna, Austria. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add the return address
Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.
Ask for certified mail
Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.
Keep the proof together
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The cancellation letter
A plain, dated letter to Sonne International asking for the cancellation, the end of every charge and written confirmation. Have the name and email on the account and, if you have one, an account or customer number to hand; our letter template fills the same shape in on screen.
