customer service sucks

I lay bye winter cloths for my kids , so i lost the initial receipt , however if you go onto the system i am positive they will be able to pick up my lay bye with the prices ect . i took out the lay bye out , in the interim all the winter cloths went on special and when i got my things i realized my husband bought the exact hoodie , trying to return the hoodie is like mission impossible the staff refuse to assist , telling me they return it at the lower price , how does this work , oyu buy sumthing for R200 and they wants to give R109 , seriously , anyone wth half a brain would say let me check on the system and call my manager and assist you , NO NOT ACKERMANS they stuck in some rule that unless you have a receipt its imposssible to return , why not print 2 receipts if your system so ancient put one in packet thta we lay bye and give us the other one so upset with this .
