Terrible service

Terrible service from the Manger At Sterns Newcastle Mall, Lynn Kalicharan. As it was valentines I was given earrings as a gift, it was purchased the Tuesday or Wednesday of the week of valentines on account. We went to the store on Friday after valentines to take back the earrings as it was bent when I wanted to wear it. We was told they can't help us because we don't have a slip and they don't return earrings, but it was not worn it was given to me bent. I am very disappointed with his kind of service.
