If just-bought items are stolen out of your car in the parking lot, don't give up hope.

Ever tried to cancel a service only to be drawn and quartered by the employees who's job it is to prevent you from canceling? It doesn't seem fair really, all you want to do is cancel a service, but if you do so successfully, some shmuck on the other end gets a negative mark on his/her record.
