Chase bank app [installed via Amazon appstore] wont uninstall on BB Z10

I installed Chase Banking app via Amazon app store and it was working fine initially. Then it needed to be updated so when I went to Amazon appstore to do that it showed a message that the Chase mobile app cannot be updated directly, it needs to be uninstalled and installed again. Since then I have tried uninstalling it a dozen times and every time it would seem its uninstalling but in reality it wont uninstall as I can see the same message of cannot be updated on Amazon appstore and also the app listed under installed apps on the Amazon appstore.
Did anyone face this same issue? How does one get rid of this app?
I dont see any option of uninstalling it on amazon.com My apps either. Please help.

What OS are you on? Chances are, it's this issue - http://forums.crackberry.com/blackbe...lysis-1058115/
