Discovery Life - Beware

I recently lowered my premiums with Discovery life on their email ***. I received proof of receipt by return email. This month the normal premium was again deducted after submitting a major amount of documentation. I want no further interaction with my broker Jose' Afonso. This was made very clear to Discovery Life. It now seems that I am being ignored as I received NO communication from Discovery Life contrary to them stating that I would hear from them within 24 to 48 hours. I need to be refunded.
