Office London Westgate Manager disgracing the company!!!

The manager at Office London Westgate is the rudest person I’ve ever come across , first she sells us sneakers which are different tone colour , we speak to her properly and tell her that we request that she gives us a different pair , she responds by saying “I don’t work for you , it’s either you want the shoes or not” , her name is Sindi apparently , I call for the directors above her to please call her to order , she doesn’t know how to speak to customers , she is disgracing the company’s name dismally and will be the cause for the decline in sales for the shop because of her attitude
