Netflix not recommended at all!

I upgraded my package and Netflix decided to change my billing date, now they keep on debiting my account until there's funds in, and the amount of unpaid debit order fees is crazy and leaving me liable for the fees. I contacted their customer service and they told me I have to cancel the subscription and open another account. Like ***# Who told Netflix to change my billing date in tje first freaking place, they making it my problem and not bothered to assist in any sense. Useless and definitely not recommended!
