How to cancel Solunion by mail
Start with your account details
Put the policy number, the name on the policy and the date you want cover to end in front of you before you write: the request to Solunion is only as good as the details it quotes.
Set out the request
Because Solunion is dealt with in Spanish, the letter is written in Spanish (template es). Subject: “Asunto: Solicitud de cancelación – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Use certified mail for the 28020 Madrid address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Solunion was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Solunion cancellation letter goes
Solunion lists Avenida del General Perón 40, 28020 Madrid, Spain as its mailing address.
The postcode 28020 belongs to Madrid, Spain, so this is where the envelope is delivered.
The letter greets the reader with “A quien corresponda,”; your own details sit under the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
