Very Bad customer service

good day please note i have experienced a very bad service from Woolworth Wonderpark branch, i went there yesterday 26 November 2022 around 8:55 at customer service since i had lay-by clothes for my son, found 5 people before me whom were complaining about how long they have qued with one cashier operating, one elder lady went to look for the manager to lay a complain about operating with one staff specially on month end, black friday weekend and almost festive season, manager was no where to be found, the que increased now about 10 to 15 people qued behind me, they also started complaining it became caotic, eventually manager was found by the elder lady who refused to go home without seen the manger to complain and her excuse was 1 person reported sick and the other one will come at 10:30. fast forward now my turn comes and i explained to the cashier that all the clothes i had on my lay-by are now on promo so what do i do? do i cancel my lay-by and take the clothes with promo for 3 for 2 or she said to me it was not possible unless i take the same clothes from the floor, she called a manager by the name of Ivy i said ohk please show me where it is written in black and white and she failed to show me saying it was an agreement between managers from woolies, funny the was a lady infronf of me who was doing the same thing but they exchanged gave her with a promo she even went to the floor to take another pair of shoe to add for 3 for 2 promo on her items. i am very disappointed with the service i have recieved especially from a manager and cashier was assisting Refiloe. very *********** staff lack customer service morals.
