APPAULING SERVICE IN CONTRADICTION OF MARKETING/ADVERTISING POLICIES AS WELL AS TREATING CUSTOMERS FAIRLY

I am very much disappointed with the appealing service I received at Mr Price(Howick).First and foremost in accordance with Marketing and advertising policies,You have to put clear and visible notices for customers to abide by. I was literally forced by a teller to buy a product that I had fitted in the fitting room,and I had been let into the fitting room by one of the store employees as well.When I got to the teller,I told her I want to place a lay-bye. She then told me that lay-byes are no longer allowed after I had already fitted the product.When I tried to take the item back to the hanger display,She also informed me I can't take it back.I was then forced to utilise money that I was going to buy baby nappies with.I currently am seating with a problem of not knowing how I will buy my babies milk.I was put under prejudice/pressure in that instance,and I really require this to be addressed as it goes against policies of Treating Customers fairly
