I want my money not a gift card.

My name is Ntokozo Sangweni I would like to share the rude and unfriendly service I got from Ackermans at Phola mall Kwamhlanga today 8th of March, I went to collect a layby that I made on the 3rd of March, before that on Saturday I went to Kwagga Edgars I found girls boots on sale so I brought them there, there was a bit of money left, I decided that let me just go today to collect the lay by because it's getting cold and I don't stay with my daughter I have to go back to school on Monday. When I got there I was assisted by the lady named Zoliswa Mabena I told her that I no longer need the Hiker boots as I have brought them at Edgars but I need the rest of the items I was told that I will get a gift card they can't refund this, I was like it's not even 30 days of me buying the items and who said I wanted to buy something else why a gift card, I asked her to show me on the policy she refused I asked for the Manager I was only told he/she is coming back on Tuesday reason I don't know the gender she refused to give me the managers name, I asked for a second in charge I was told she(Thoko) was on Lunch, there's nothing they can do, I left there hurt I have layby at other Ackermans shops in town Pretoria, I have never received such service, I don't need the goods any more I want my money back and I don't want a gift card, I want my money because now I had to buy clothes for her else where I don't need them anymore.
