[Wordpress issuses] starlightcinema on "Changing account details and cancelling charges to credit card."

I wish to cancel Akismet on the website http://www.sonuspianoquartet.com.au. I no longer manager this site and the new owners do not require this service. How do I cancel the charge to my credit card?

I wish to delete the Starlight Cinema connection to [email redacted].

The blog I need help with is starlightcinema.wordpress.com.
