Disrespectful workers in retail

Went to purchase a pair of sneakers at pep in Westwood and my experience In the store was terrible from the store manager down to the floor staff , a pair of sneakers witch was on sale for r39.90 when we got to the till it scanned at r89.90 so the manager went to check and then said it's marked down to r89.90 so y have a price for r39.90 to mis-lead customers the manager and staff were very rude to say the least about what transpired , I was embarrassed In front of other customers and my family which is unacceptable .the manager of pep her name is sli she is arrogant and disrespectful she shows no remorse for mistakes in the store
