Poor Customer Service

My name is Lizzie Barnes. On the 05-08-2018 I paid by debit card an amount of R1000,00 at Pick n Pay Thabong Sebokeng. The supervisor told me that the transaction cannot be voided and the only thing to be done was to cancel the sale. I was told to wait for 48 hours before they could do a refund. Another thing I had to go to the bank to withdraw a statement that will be proof that the money transfer had gone through. On the 07-08-2018 I went back to Pick n Pay for a refund I was sent back again. On the 12-08-2018 I went to the bank again to withdraw a statement and took it to Pick n Pay Sebokeng, unfortunately the manager who did not have a nametag for me to recognise his identity saying he is Papi told me that I should leave the documents with him so that he can attend to the matter tomorrow because the settlement department is closed today and there is nothing they can do to help me. The service that I received was so very very poor. Every time I withdraw a statement from the bank there are charges from the bank and I have to use transport to get there. At first I was told to wait for 48 hours but now is over a week and I still haven't received my refund. It is so frustrating and so inconvenient.
