Got charged double after app was updated for bugs

I purchased the live access subscription on 6/6/2015 to watch the season. I had to update my app because of new update for bugs that WNBA put out. Unfortunately when I opened the app again and logged on they charged my credit card again for another subscription. I have been e-mailing them back and forth but they said I never purchased the first subscription even with proof on credit card. I dont recommend the update.
