How to address the envelope

  2. Put your own address on it

  3. Send it certified

    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.

  4. File the receipt with your copy

    The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request.

The letter to send

The request itself is short: MUDWTR 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.
