How to cancel Prosetecnisa by mail
Note your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Prosetecnisa holds, so the request can be matched to your account.
Set out the request
Prosetecnisa is based in Spain, so the letter goes out in Spanish, built from our Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Send the letter to the San Vicente de Barakaldo mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Prosetecnisa 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.

Before you cancel Prosetecnisa, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
