Customer No longer Priority but a liability!

On 22/07/2018 I visited Sterns N1 city & wanted to purchase two gifts for my niece & nephew as 21st gifts. I noticed a watch that i wanted to purchase for my niece; however there was nothing that i liked for my nephew. I then decided to go over to American Swiss to see if there was something for him. I then purchased a watch for him; while at the counter i noticed that it was 16:40 so i informed the female at American Swiss that i need to go back to Sterns to purchase the other watch. This lady then called Sterns to advise them that i had on a red dress & i would come back over to Sterns to purchase the watch. When i went over to Sterns @ 16:44 the shop door was closed & the lights was off. I then knocked on the door & Olwethu then came & advised that the store was closed. I informed her that the lady of American Swiss then contacted her to advise her I would be back to purchase the watch. She kept on insisting that the store was closed & the till was off. So if your shop says 17:00 closing time, why is it that @ 16:44 everything was off. I was so angry, and then went to Sterns Canal Walk to purchase the watch. The service is poor, i wasted my petrol to get to canal walk, as she refused to do the purchase. Gone are the days when a customer was a priority. Next time i will know not to go and purchase anything at Sterns N1 City.
