It has bugs- needs urgent fixes

The app needs to be fixed, it has claimed passes I have not used and there is no way for me to correct! It claimed passes as used even before I purchased them!
I contacted they customer service and they basically said nothing that can solve my issue. If the issue is your app fix it! Do not make additional issues for the end user!
Bad! Bad! Bad!
