Unprofessional, unpleasant and bad customer service

On Saturday the 23rd of May I went to Jet at Cresta mall, so there I bought pajamas which were priced down to R80 and when I got to the till the cashier who assisted me was full of attitude and all she said this price is wrong and then I asked so now what must happen because that's what's written on all the pajamas and she just undermined me and ringed the "apparently correct amount" and when I asked why she rolled her eyes. I have never seen such a dirty and filthy and unprofessional and unpleasant customer service . I was so disappointed with Jet and even the security was dismayed, he tried to assist me. That lady needs to go home if she doesn't want the job
