How to cancel Mmt Seguros by mail
Gather your account details
Check the policy number, the name on the policy and the date you want cover to end before anything else. A request that does not match the account on file at Mmt Seguros is the easiest one to set aside.
Put the request in writing
Postbye writes the letter in Spanish from our Spanish template, because Mmt Seguros's address is in Spain. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Mmt Seguros to end the subscription, stop all further charges and confirm in writing.
Post the letter
Use certified mail for the 28010 Madrid address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
File the receipt with the letter. A Mmt Seguros charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
