How to address the envelope
Use the address letter for letter
Address the envelope to Ronda de la Comunicación 2, 28050 Madrid, Spain. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
Add the return address
Your name and postal address go top-left on the front (or the back flap). If the letter cannot be delivered it comes back to you, which is itself evidence of the attempt.
Certified mail, not a courier
Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Madrid is traceable from the article number until it is signed for.
File the receipt with your copy
Hold on to the letter copy, the receipt and the tracking page.
The cancellation letter
The request itself is short: O2 is asked to end the account, stop the charges and confirm in writing, with the account number, the phone number or service address being cancelled and the name on the account where the brackets are.
