Pretty sure this is the end for me. I put in $200-$300 per month for 6 years and now I spend more time trying to log in than playing. If this is the level of competence of the programming protecting my financial and private information then you don't deserve my custom; my data is at risk, clearly.
Either you:
1. do not test your code before release,
2. ignore failing code if it is found,
3. are not competent programmers or testers, or
4. simply have such a low opinion of your customers that you release the code anyway.
5. or maybe you want to kill off the game and move on but dont want the backlash?
If none of the above, and you obviously know of the problems, then why not roll back?
