POOR CUSTOMER SERVICE

I went to PNP Clearwater at around 13:00 when i was about to pay the lady(MBALI) said she can not assist me i have to go back to the Que(with an attitude) when i ask her why she said she already called another customer she can not help me, l asked her how come because when i come to her she was not busy she was busy with her phone, after a second she called a white lady and she assisted the lady. i asked her just because I'm black u dnt want to assist me but yet u are assisting the white lady she started shouting at me as if m her child, i asked to speak to her manager she said go n find the manager ur self. i spoke to this other guy by the name of Nathi he said he is the manager i told him my story and he ignored me and he continue wat he was doing, Pnp staff have bad attitude it seems as if they are doing someone'\s favor by working there. how i wish you can fire that ***** she does not appreciate her job
