It appears your account was closed shortly after you posted this forum thread.
However, the account you used to post here was only a few months old, and had never bought anything from us. We don’t even have a credit card on file for you.
If you’re being charged, it’s for a site in a different WordPress.com account. If you’re not sure what site the charge is for, please search for the charge at https://wpchrg.wordpress.com/ – enter the transaction details on that form, and it will tell you if that charge exists on our end and what site it’s for.
You can also use the Contact Support link on that page to contact our billing support team directly for further help with this – to track down the transaction we’ll need to get some additional information from you which we cannot discuss here in the public forums.
