UNPROFESSIONAL MANAGEMENT AND THEFT.

So I purchased a chain with a 21st key for my daughter @ STERNS VANGATE MALL BRANCH. Not knowing my husband purchased same gift at a different branch. Today I went to exchange the gift and I was assisted by a gentleman who then needed assistance from management. The assistant manager with the name XOLISWA was there. SHE WAS UNPROFESSIONAL/ RUDE AND DEFINITELY HAD NO IDEA HOW TO HANDLE THE SITUATION even though she is in a management position. I paid with my bank card and that is known as a cash purchase however she told me they do not have cash and I can come back the next day because she is busy. I asked her how can I pay R150 uber there again if I am coming from Strandfontein. She told me that was non of her business. I waited in that store for a hour as that gentleman who is a staff member ran from 1 Foshini group store to another to get help of doing my refund of R769. When I said I am going to write this review and approach the ombudsman Xoliswa the manager got annoyed and then called head office who said that they can refund me to my bank card but the money will only be available in 7 to 14 working days. I then asked how can that be because when I paid for the item they did not wait 14 days I paid them immediately and I demand my money back immediately. She told me that she don't care what I want and I can write my stupid report as she don't have the money to refund me and I must just come back when she has the money. NOW HOW DOES STERNS / THE FOSHINI GROUP NOT HAVE THE STAFF TO HANDLE IT PROFESIONALLY. HOW DO SUCH A BIG BRAND WITH MANY BRANCHES IN 1 MALL NOT HAVE THE ABILITY TO GIVE ME MY R769. ALSO NOT TO FORGET I NEED TO UBER BACK THERE WHICH MEANS I WILL BE SPENDING MORE MONEY TO GET THERE THAN MY REFUND ITSELF. I AM DISSAPOINTED IN THIS AND I WILL BE CONTACTING THE OMBUDSMAN REGARDING THIS. I FEEL THAT XOLISWA AND THE STERNS GROUP SHOULD TAKE FULL RESPONSIBILITY FOR THERE UNPROFESSIONALISM TOWARDS ME AS A CONSUMER . PLEASE ADVISE HOW I CAN DEAL WITH THIS LEGALLY REGARDING MY EXPENSES PAID FOR GOI G THERE AND MY NON REFUND.
