not interested in customer service

On 5 august I went to the red square in centurion mall to buy a foundation for my skin tone I thoroughly explained to the lady that I'm travelling to the us this weekend and I wanted a nice long lasting foundation she then rejected me by saying what I have now suits me I shouldn't worry about changing I politely told her I needed to change but she kept on embarrassing me by calling her other colleagues to check my skin, I usually go to Tshepo at the centurion edgars but she was busy, I regret why I even considered walking in there
