Why do you think you were charged twice? Where are you seeing the double charges?
Are you see 2 charges on you credit card? It can happen that one of the charges appears as pending, then a confirmed charge is added, and sometimes there is a delay before the pending charge is removed from your account. Is this possibly what you are seeing?
If you indeed see 2 confirmed charges from Fizz with the same date, then you will need to contact Fizz support for a refund. It could be a billing glitch. The only other explanation is that you have 2 accounts/plans charged to the same credit card.
