Background
I did some pro-bono work for a community organisation a year back which involved establishing a website prototype built from commercial third party services. Some services had a yearly recurring service fee, and during the prototype stage I - rather foolishly in retrospect - paid for a couple of these services with my own credit card in order to speed up the development process*.
The community organisation did compensate me for this at the time and I had every expectation that any recurring billing arrangements currently linked to me would be transferred to the organisation prior to the next yearly payment.
The organisation then had a change in management and direction; from a forward-thinking computer-literate president to one of those crypto-luddites we often assume don't exist in the 21st century. So now the organisation discards various "online" initiatives of the previous president, including this website prototype. This is irritating but I can accept it - it's the nature of pro-bono.
Fast forward half a year, and for various reasons I have given up on helping this organisation**. So I handover all remaining digital assets and instruct them either de-link my credit card from any services they choose to keep - or close the services prior to the next auto-renewal charge. Since a few rare services for some insane reason I can't close myself despite being the owner of the associated billing account (credit card), I choose to trust the organisation to push through the appropriate business letterheads, etc. before I get charged in six month's time. They fail to do this.
I am now intend to interact with the service provider directly and get the service account closed and any errant auto-renewal charges refunded where applicable; regardless of any procedural nitpicking by the service provider's first-level customer helpdesk. I am after all the person actually paying the service. Due the community organisation's self-same sloth and incompetence, the services still have the same passwords and personal contact details as when I first handed over the prototype and instructed them to change these credentials.
Question
Is possession of a digit asset nine tenths of the law?
If I am paying for a service; have no contractual obligation to the organisation for some ongoing gratuity or donation by way of funding this service; and I have (re)changed the passwords to assert sole control of the service account*** - is the service account essentially mine to close?
* The organisation's sloth should have been my first clue.
* * Inept management practices; dispirited membership and volunteer outflow; a sharp swing towards regressive solutions; systemic structural flaws in the parent organisation; and so forth.
* * * They also haven't exerted any "habitual expectation" through use or access to the services I'm paying for.
