Hi @Kent,
Sorry for the delay in seeing your post. The Three Community is a public forum of mainly other customers, and staff wouldn't be accessing your account in response to your post here, so we won't be able to definitively answer this.
The best advice would be to contact customer services. They'll hopefully have more information about how this happened, and can check if they have any options to support you as this has been impacting your bills for a long time now.
Thanks,
Jonathan
