It's not whether they are legit or not in question, it's whether they take a full account of the problem. So far only problems about high traffic were reported on their official twitter, and here we're definitely dealing not with a problem caused by heavy traffic. Either they do not take the account, and in this case people can be in trouble and warning those who have not spent the money yet are worth to be warned, or they do take the account, and in this case it means they don't want to admit the problem publicly for some (maybe PR) reason, which is neither a good sign.
