Is it possible to somebody to tell me how to suppress an account ?

Hi,
As didn't receive any useful answer on the french forum, I try on the english one !...
Because of difficulties to connect my nabaztag, I have created 2 accounts with 2 email adress.
Now one of this acccount is operational and I would want to supress the other..
Could somebody help me
I already wrote a few times to the "support" but it seems that it's only a "name" because I am always waiting for one answer..
Thanks
Dan
