*********** disrespecting supervisor

I went to Makro Germiston to shop i am not a regular customer but well today decided to go and shop as i viewed their pamphlet and most of the items the prices were reasonable, as i got to pay, point station i saw the price for 5litre oros for 2 it's R140 while on pamphlet it was R65 for two i ask thz cashier and the cashier called tje supervisor the supervisor called the manager her Name ENRATE, the manager was very rude unprofessional and very *********** to me, she answered me in very aggressive manner she said"why i didn't read the displays for apology! She she won't override actual what exactly i am expecting her to do... In a, polite manner i ask her can, you please talk to, me and explain in calmness she said what for, i ask her can u call your manager she, said she is store manager the one i am looking for they are, on street striking i ask for her name since she didn't have a name budge she refused and i had to go straight to customer service and raise my concerns was verh ****ed with her service i wonder how could a big company hire such unprofessional manager it gives me the impression of you don't train your stuff about customer serve, the service i receive was, very very poor worse she **** to say she is a store manager and even took advantage that i am very young, i believe we must we must provide equal best customer service to customer wether is gender, race or what.. I real had a bad experience from disrespecting manager.s
