lack of training

what management fails to do impacts the customer drastically. Today I purchased a shirt from edgars ballito junction and normally i dont have an issue but today was a unexplainable experience the cashier didnt remove the tag and didnt know how to deal with an account customer. I have walked out of the store and it never beep (so i couldve easily ****** the shirt fyi) i get home and see the tag now im left with an inconvenience.. PLEASE in future take responsibility in training staff cause they are the ones that bring business into the store and they are the ones that the customer deals with last.
