Yea, because they're just going to let you play & recharge for half a year, then when you get bored & quit they'll just give you back half of your money because they don't need to be a profitable business or anything.

Do you buy games play them for a few days, then get a 50% refund for returning the game?
Do you go to the movies watch half of the movie & get a refund for not watching the other half?
Do you eat half of a meal at a restaurant and get half of your money returned for not eating the other half?

Be realistic.
