No premium features at all and double charge on credit card. How can I get help?

[albagerardo]

I was trying to get premium
9 mxp for 3 months.
I entered my credit card info and got a message saying the charge couldn't be completed, after that I received an SMS from my bank telling me the charge was successful and then a 2nd message with another charge.
I have no premium features at all and a double charge on my Credit card, is there any way to fix this?
