Bad experience

I went to Pick n Pay Hyper on Friday the 6th of December, to get a refund on the items I bought, the lady who helped me was Maria, she was very funny to such an extent that when she was doing the refund she threw money, I have even asked her if she was done and with the long face she said yes, this is very disappointing, especially at the return counter, I felt that there was no customer service at all
