Horrible customer care!!

This is the second month that Affinity Health debits my account before my payday. I phoned last month and was assured that this will not happen again, but yet it did. They apparently check your account before your debit date and if there's money, they take it!! So please explain to me...who will provide for my family now until i get paid? Those idiots sitting at the back have no consideration for a person's circumstances. And the beauty of it is, they dont even get the flack! The poor people answering the frontline calls must deal with it. I want this **** to stop or i will cancel my membership! Who gives you the right to take people's last food money before they get paid???!!! And i bet you wont even give my ****** money back today!
