Being charged for a Flex device that was returned.

[AngryXCustomer]

I was erroneously sent a second Flex which was immediately returned. However I am still being charged for it. I was chatting with two separate people who strung me along and tried to upsell me for an hour and then told me they couldn't help. Is there anyone with a brain I can get to help me?
