How to cancel Qconcurso by mail
Start with your account details
Put the email on the account, the name of the plan or course bundle and the date of your last payment in front of you before you write: the request to Qconcurso is only as good as the details it quotes.
Write your request
Postbye writes the letter in Brazilian Portuguese from our Brazilian Portuguese template, because Qconcurso's address is in Brazil. It opens with the subject line “Assunto: Solicitação de cancelamento – [your name]” and asks Qconcurso to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Use certified mail for the 02710000 São Paulo address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
It shows the date Qconcurso received your letter. Check your next statement: no Qconcurso charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Qconcurso cancellation letter goes
For a letter to Qconcurso, use Avenida Professor Celestino Bourroul 100, 02710000 São Paulo, Brazil.
The envelope is going to São Paulo, Brazil, so the postcode 02710000 must be on the front.
The letter is addressed “A quem possa interessar,” and its details block uses the labels Titular da conta, Endereço de cobrança cadastrado and E-mail cadastrado.

Cancelling a learning subscription
Learning platforms push annual plans and free trials that turn into paid ones, so the request should name the plan and the date the trial or term ends.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
