Earrings ordered a month ago - no delivery

We have had the worst experience at Browns. Both my husbands wedding bands and mine are from there. Over Christmas my husband a pair of earrings for me. On 19th Dec to be exact. We did this online with the help of the Gateway store. I was informed that it would arrive before Christmas. We still have not received the earrings. There has been limited feedback from Browns. Eventually this weekend we were told that we would receive the earrings on Monday. Then the social media team said it was only being posted on Monday. The most uninspiring customer service experience.
