How to cancel Monabanq by mail
Find your account details
Monabanq will look your account up from what the letter says, so check the account email, the last four digits of the linked bank account or card and the membership tier first.
Write your request
Postbye writes the letter in French from our French template, because Monabanq's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Monabanq to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Address the envelope to Monabanq, Lille Cedex 9, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
Delivery confirmation is your evidence that Monabanq was asked. Watch the next statement or two for any further Monabanq charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
Monabanq's own site is monabanq.com. Check its account and billing area first to see whether the plan is billed by Monabanq itself or by a partner.
