The addresses we hold
Everything we hold on where Three takes its post: the RG2 6GF Reading delivery point for a cancellation letter, any second address, and how to send it so the delivery is on record.
Where the letter goesMailing address
Three450 Longwater AvenueRG2 6GF ReadingUnited KingdomThe United Kingdom address on file for Three. Postal code RG2 6GF.
How to address the envelope
Copy the address exactly
One address block, copied whole: 450 Longwater Avenue, RG2 6GF Reading, United Kingdom. If any line differs from the card above, start the envelope again.
Put your own address on it
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.
Buy the certified service
Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Reading is traceable from the article number until it is signed for.
Keep the proof together
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.
The letter, written out
The request itself is short: Three 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.
