Bad service delivery

On monday 22nd of June I went to Ackermans in polokwane corner Landros Mare and Grobbler street,ok centre to buy a pair of shoes,I stood In a long queue with 1 cashier serving,when i got to the cashier the shoes i was buying did not have a price,the cashier called out for help with the price and it turned out the other pairs of shoes did not have a price attached as well,so the cashier said to me there is no price for the shoes,what should i do,i asked her why are you asking me and how do you have the shoes on shelves if they dont have a price in the 1st place,I also don't know how to get the price,she then called a guy by the name of Jacob,who did not greet,did not apologize for the inconvenience but instead said to her in my presence ,what do you expect me to do,how will we sell the shoes without a price,simply tell her she cant buy them,I left the store without the shoes and that pair was the only size left,my heart was so broken
