How to cancel Attainify by mail
Get your account details together
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Attainify is the easiest one to set aside.
Put the request in writing
Ask Attainify to cancel the account, stop all further charges and confirm in writing. Postbye prepares the letter from our English template, with the subject line “Subject: Subscription termination – Attainify”.
Mail it with tracking
Mail the letter by certified mail to the Las Vegas address in the next section, and keep the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Attainify 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.
