Charging for canceled package

Hi. Im so disappointed at the service of afrihost.. I've been with them for over 10 years and this is how they treat an ongoing client. I have a few packages at afrihost and recently canceled 1 of them through the afrihost client zone.. The package I canceled in October of 2020 already is no longer visible on clientzone but my account is still being debited for this package. Now afrihost is giving me the run around sending me back and forth. Meanwhile still charging me and refusing a refund. What can I do about this.
