How do you get your parents to give you something back?
Don't ask straight out, give them time. Be really well behaved and do what you are told. Do extra chores around the house, be cheerful when you are at home and around your parents. After a while of good behaviour ask for it back (but don't demand it) if they say no just say OK, they will have noticed your good behaviour and it will only be a matter of time before you get it back and don't continuously ask for it back it will only make them keep this thing away from you longer. After you get it back though don't go back to bad behaviour because your parents will know what works on you and take it away as quickly as you got it back. Hope this works.
