Wrong billing, and problems for terminating services


I don’t understand why I have been billed 2 on june & july ($14.2 & $13.8) despite the fact that my current plan indicates “Remaining free node hours: 642”

Furthermore, I can’t find a way to terminate my services. I currently ows 2 stopped services, but cliking on “Terminate” seems to fail.

Thanks for your help.
