disgusting customer service

One saturday 19/03 i visited the cresta Pick n pay CLOTHING branch to do an exchange i was assisted by a cashier named portia. She had very bad attitude, she threw the book to fill out at me n didnt explain which fields to complete and then grabbed it back. She did not greet ,smile or make eye contact. Her over all customer experience was terrible and she gave the impression that she did not want to be there. Her name tag said portia but on the slip it states that the cashier is Jane mamabolo, which is worrying as it does not correspond.she gave my copy of slip without even looking my way.
