Worst customer service

I was at the branch at springs mall yesterday 19 december 2025, Zweli Brta was my assistant and I asked him for a puma sneaker size 11 but they had 10 on the floor both of them were on The floor (dirty) one had even a black mark on it, which i then told them Iam actually looking for a size 11 Bandile the store manager said size 11 is on the system meaning they have it but then we all three agreed to say let me take the size 10 so my son can fit and if its small then I will bring them back,I did bring them back but now they are refusing to take them and claiming i made them dirty when I found them in that condition,Bandile phoned his regional managerNomasonto Mdaweni who is extremely rude and refuses to hear the side of my story and standing with her store assistans,I explained to her that this is the condition I found the shoes in but she is not hearing now iam left stranded because I need the shoes or my refund so I can purchase them in another store since they customer service is -0 The store Manager Bandile even said he was going to ask the security guards to escort me because I was refusing to leave without my refund,the service is so appalling they are so rude side step needs to do better
