Very Disappointed

I visited the Grace the brand store in East London on a visit there and bought a pair of earrings. When I got home I found that the earrings were both right hand earrings and so the gems could not be seen when worn on the left. I mailed the customer support team to see if I could get a replacement earring for the left ear. The team was not helpful at all and told me that I needed to pay for the courier as I don't live near the store. They stated that the online and physical stores are not linked and so they can't help me. I am extremely disappointed and irritated as their jewelry is not cheap. Very unsatisfied!
