The addresses we hold
The address a cancellation letter to Umobix needs, and every other address we hold, starting in London: copy the lines exactly and the envelope sorts itself.

How to address the envelope
Write the address as printed
Address the envelope to Hatton Garden 63 - 66, 5th Floor, Suit 23, EC1N 8LE London, United Kingdom. Everything on those lines matters for the sorting machines, so nothing is abbreviated by hand.
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 Umobix has moved.
Ask for 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 what the post office gives you
The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.
The cancellation letter
What the letter to Umobix says: one clear cancellation request, no reasons given, the account or subscription number, the email the plan was bought with and the address or devices it covers quoted, and a request for written confirmation.
