Hubic is embarassing and still sends me invoices

I was paying for the Hubic account even after I realized this service is dead and buried. No new Linux client since 2015, and that one "in beta", e-mails sent in French, despite my language settings, or the fact that the "support link" in an e-mail I just clicked from gives 404.

Then, it stopped automatic payments. I don't know what happened, but I assume the PayPal support got removed. So I went to pay two outstanding invoices (because they would bill me for the next month despite me not paying for the first one) and deleted my account.

And now I'm getting e-mails with invoice, after my account has been deleted.
