How to cancel Protego Biopharma Inc by mail
Note your account details
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 Protego Biopharma Inc is the easiest one to set aside.
Put the request in writing
The letter asks Protego Biopharma Inc to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Subscription termination – Protego Biopharma Inc”. Postbye fills it in from our English template.
Mail it with tracking
Use certified mail for the 92130 San Diego address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
File the receipt with the letter. A Protego Biopharma Inc 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.

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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
