STERNS ATTITUTE STINKS

I recently received a pair of earrings as a gift and it was too big. The person that bought it gave me the receipt and everything. The earrings are still sales in the packaging but sterns cannot exchange it I don't understand why. The staff at Chatsworth Centre branch are so rude. The counter assistant tore the box and said I tore it and then she went and bluffed the manager something.The manager himself has no customer skills and is more rude than the staff. They don't care about customer service but maybe try moving them to gateway branch and see how polite they become
