After you file

Ok .. so do you also go to a fast food restaurant, order & pay for the food and just because you decided not to eat it when it comes you expect a full refund ?  That is the same thing with TT ... you paid for the use of the program and still have access to the same but just because you choose to not use it you expect a refund.
