missing product, do not want to change

<p>On Saturday 10 June 2017 I purchase an item from Game Gateway, when I arrived home and open the item I see there was items missing I called the store and the manager agree to change the item for me, I also informed him I was not near Gateway and Westwood is closer to me, he informed me I can change this item at westwood, I went to westwood yesterday, the staff and manager (lorraine) was rude and unhelpful. They said they cannot change the item as all Game stores stock different items and they do not stock this item. Now they want me to go to Game Gateway which is out of my way to change this item. The product had missing items, they will need to return to merchandise not add to their stock as this item cannot be sold to another customer. Why is Game service so bad? </p>
