ChamRue du Saule Trapu 1191300 MassyFranceThe France address on file for Cham. Postal code 91300.
How to address the envelope
Write the address as printed
The front of the envelope carries Rue du Saule Trapu 11, 91300 Massy, France and nothing else in the address block. Check the 91300 digit by digit before it goes in the post.
Put your own address on it
Top-left, your own name and address. A return address is what the post office needs to send the letter back if Cham has moved.
Send it by certified mail
At the counter, certified mail costs a fee on top of the postage and comes with a mailing receipt and a delivery record. The tracking number on the green label is what you follow.
Keep the records
Your copy of the letter, the mailing receipt and the tracking record belong together in one file.
The letter, written out
The request itself is short: Cham is asked to end the account, stop the charges and confirm in writing, with the name and email on the account and, if you have one, an account or customer number where the brackets are.
