Sorry no exchange after just 5 days

I finally got a job again and to spoil myself I went to Game to buy myself some jewelry. The original set of earrings and pendant that I wanted was just out of my reach to buy so I took my second choice. When I got home my husband said why do I always take second best so I decided to go back and exchange for my first choice. I called the branch on Tuesday and spoke to the lady at the Jewelry counter and she said yes its fine I can come in and exchange. On Thursday 5 days after I bought it I went in and after waiting for 30 minutes was finally helped and then sent to customer service. There I was told to wait for the manager and he then told me sorry they cannot exchange as it was earring and a hygiene thing. I told him what about all the people that try on rings every day never mind that I called before hand and was told to come in. I was so disappointed and upset that once again I had to settle. Why could they not exchange and then just clean the jewelry again to disinfect it. And another point there are no boards or signs that say you are not allowed to exchange Jewelry. I will never support Game again and I will never say a good word about them again.
