Awful service from cashiers

I went to ackerman's umlazi megacity branch looking for toughees, I found the right size than went to the till to make payment ,I got to the till and the cashier "ayanda khusi" told me that there is no price tag and I should go get another pair with a barcode ,due to the fact that I got a spine injury I than sent my 7 year old daughter to get it cause she knew where the shoes were ,the cashier than rudely told me to move from the till cause she wanted to assist people who knew what they wanted ,I asked her who's fault was it that the shoes on the shelves has no price tags ,she than said it's not her fault either cause I decided to take the 1 pair without the price tag than send a child to fetch the tag so shes busy and don't have time to waste
