I gave it up voluntarily. I had no need for it for a time and so I just returned it. I don't understand the idea of having arbitrarily limited amount of numbers and selling them. A lot of companies just got them for free and are now selling them for huge bucks because rather than do what I did -- return public good you are not using -- they decided to hog it until such time it becomes scarce good.
