Canceled order

I placed an order with Zando and they sent me an email notifying me that they've canceled my order. I immediately notified Payflex and forwarded them the email I received from Zando about the cancelation. Zando has closed down and Payflex is refusing to stop deducting money from my bank account even though I forwarded them the cancelation email from Zando. I have been communicating with Ethan who only engages when I send an email but other than that they aren't attending to it or trying to resolve it.
