Tell that to FastMail, who have pissed me off by deciding to end-of-life the "lifetime" 16Mb member account I set up for my father with a one-time $15 payment.
16Mb is modulo zero these days, but it's enough for him - he just deletes some emails when it gets full. He also gets imap access and FastMail's spam filtering, which is really very good. I can also assign him an email address from a domain that I own that is associated with my FastMail enhanced account.
I don't want my $15 back. What I DO want is for FastMail to honour our existing agreement, which was a LIFE-TIME 16 Mb member account in exchange for $15.

Text of their latest email is below the line:
=============================================
Back in January we contacted you with some important information about your @.* FastMail account.
We're now contacting you again to remind you that from 31st July, 2017 our 'Member' level plans will be discontinued.
To continue using your FastMail account after this time you'll need to select one of our current plans. Please note: your email address will remain the same.
As a long-time FastMail user we're offering you 50% OFF all upgrades until the end of July, which includes our already discounted multi-year subscriptions.
And if you upgrade now we'll also add all the remaining time until 31 July for free!
As an added bonus we've also given you $15 credit to put towards your subscription, which is equal to the amount you originally paid for your account.
This means if you were to upgrade to a Basic account today for one year, with the discount and account credit you are effectively getting FastMail at no charge until 31 July 2018 with a massive 2 GB of storage (up from 16 MB)!
