Stop b*tching?
Come on... you're getting a free service for nothing. Talk about looking a gift horse in the mouth.
Google is first and foremost a business. As a business with limited resources, they have to prioritise what they do next, they can't do everything at once. Even if they automatically *DELETE YOUR ACCOUNT* when you reach the limit, it'll still have pretty much no impact on their bottom line, because the proportion of people getting there is so small.
So I would say you should be thankful they even took note of the issue (if they did).
Remember: Google don't owe you a damn thing - not even to give you the time of day. You're using a free service, that works astonishingly well and is more reliable than many paying ISP's for almost 100% of the time. Stop b*tching!!
