Disgusting service

I got a reebok takkie as a gift however it was a size to big, I decided that i would then go to the footgear in the promenade mall Mitchells plain, at first we looked around to then just exchange the takkie for something that i liked i spoke to one of the employees, i explained to him it was a gift however it does not fit, he advised they do not have this in takkie in stock. I told him that i had a look around the store however, I didnt see anything i liked and if its possible for a refund what he said next shocked me. He advised that we ask the person that bought the gift to EXCHANGE it as the person bought it in access park kenilworth. I made it clear to him that it would be very rude to advised them to have it changed for me. He called the manager i explained that we had a look around the store and there was nothing if we could maybe receive a refund for the cash so we can go ahead and browse around, she advised that currently the store is not busy so they dont have cash in the store and i didnt argue my husband and I advised that she could take out number and call us when the exchnage could take place she then said she dont know when it will be. Fast forward to 22nd of March we called the store as we have not received any communication the manager answered and advised that she tried contacting us but now is a bad time as they dont have any money in the store amd when she called the refund was processed which i cant understand because dont you need the receipt to log the refund?, i advised a complaint would then be logged and requested her name she then told me that we could come on a weekend which i advised we had things to be done and then again she said then come on monday which i advised i had worked i then told her let me have the complaint logged because the 30 days is almost over i cant be fighting a full month, she told me then its okay we can come on at 2 she will then have it processed. My husband and I went to the store and when i tell say the service ia terrible i mean it. The manger had the audacity to ask why would we buy something in kenilworth to exchange it in Mitchells plain why would we then buy it even though i made her aware it was a gift, and then she also asked why dont we come in the week as its very quiet I advised i made her aware in the beginning i work as well knowing not even an hour ago she advised we come down to the store. Whilst processing the refund we saw on the sheet there had been two refund exchanges done that same day and the service from the manger and the sales employee was disgusting very very disappointing
