Not getting back to me

I bought a ipod nano 7 generation from game, I noticed that the exercise function was not working properly so I decided to take it back, I went straight to the Manager Drayl. He took me to customers service were he instructed the lady there to give us a cash back voucher and this people that that we came to ***** them as they wrote on the back no cash refund, for ipod nano, this is contradiction because they do not have an ipod in the shop , the manager said if I give him a week, he will get one from lichtenburg, I accepted and left the store, I went back after a week and he refused to come to the front, as I sent his assistant manager Sydney satisfied, to call him, then a week later now three weeks later I saw him at the front desk, he said we must send it for repairs I asked him why didn't he do that in the first place, anyway I agreed, he told me 21 working so I went back to him, after 21 days and he still says that I must wait 2 weeks, this is totally unacceptable, I am not going to wait, game must replace this item with a brand new ipod, I am not waiting longer, please discipline this store they are very *********** when dealing with customers.
