Your staff attitude will be the cause of your shutting down

I am a very regular shopper at Edgar's Melrose Arch. This is the second time your staff attitude has left a very bitter taste in my mouth. I went to the Estée Lauder counter today and a lady by the name of Portia (from the Sisley) counter assisted me as she was sitting at the Este Lauder counter. Once I got the items I needed, I asked if I could pay and was rudely directed to the main tills which is a distance away. I politely asked if I could pay at one of the cosmetic counters as it was cosmetics I was purchasing. Next minute I was being screamed and yelled at for no valid reason. This Portia is has an unstable mental state! After shouting at me she stormed off and left without me paying for my products. She actually made a rather embarrassing spectacle in public. There was exactly ONE other customer at the cosmetic section. Another kind and helpful lady came up to me quick and rang my stuff up at the counter next to where I was standing. Simple and efficient. This is not the first incident I've had at this branch. On another occasion, I stood at the Este Lauder counter waiting in the que to be assisted and when it came to my turn, the sales lady walked away to help someone at another counter. Your store is always extremely quiet and I can assure you that it's due to the bad attitude of certain staff members. I did not appreciate being screamed at in public. I doubt you'll be seeing me at that branch anytime in the near future! I won't be surprised if this store closes down very soon! Totally pathetic. I expect an apology from this Portia!
