You don't have any real control over that account. I can think of ways to lose an account and while not all of them are very likely, I wouldn't be surprised to see all of them happen in, say, the next five years or so if they haven't already happened:

The database could get corrupt or the data center burnt down and if the service provider hasn't a good backup strategy your account could be gone. The same goes for unauthorized access to the database or your account, it can be removed without your say so. Or the service provider is shut down by the government for whatever reason. Or worse, your country decides that the service provider may not operate in your country and that all accounts of people from your country should be removed and they comply. Or some governmental agency takes all the servers of your service provider and won't give them back (in one piece).
