How to cancel Hellofax by mail
Find your account details
Check the account email, the plan or product name and the invoice or order number from your latest receipt before anything else. A request that does not match the account on file at Hellofax is the easiest one to set aside.
Put the request in writing
The letter asks Hellofax to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Hellofax”. Postbye fills it in from our English template.
Send the letter by certified mail
Mail the letter by certified mail to the San Francisco address in the next section, and keep the tracking number.
Save the tracking record
The receipt dates your request. Look at your next statement for any Hellofax charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
