It has been over 5 months since you discovered the software issue that some iPads on data plans think they are on Prepaid and tell users they are out of data. All of your fixes are temporary. You continue to sell iPads knowing they do not work properly, are you going to compensate the people that bought iPads from you and continually have problems?
Since the problem is between the iPad and your network you cannot blame it all on Apple.
