Worst Customer Experience

On the 2nd March 2019, I visited NWJ in Canal Walk. I walked in along with my fiancé, aunt and sister. The sales lady Carla was unfriendly and had rested her head in her palm while she poorly assisted us. I then decided on which ring I would like, she advised me she would contact me on Monday and let me know the procedure whether the ring should be made or resized. By Wednesday the next week when I did not receive a call, I called her twice and left messages. Eventually I got hold of her and I asked to order the ring in my size an H in time for my wedding. On Wednesday, the 13th March when I am supposed to collect the ring on Friday the 15th March in time for my wedding Carla contacts me and advises that she had the ring in a size K. And If I want it to be sized to an H, I would have to make a payment for the ring. Which I refused and could not understand how suddenly the incorrect size was delivered. I then requested to speak to the manager and Carla the sales assistance raised her voice shouted at me and said there is no manager in the store. And I made mention of the poor service I have received she screamed at me stating she provided good service and that she will tell the manage to contact me refusing to assist me in getting my ring here before my wedding day. Not only was I treated badly but I will not have a ring for my wedding day!
