Poor service

I bought shoes for my sister in laws dayghter on 23/12/2019 I was helped by Nthabiseng Musi whom I asked what time they close, she said 18:00,and I went to the store on the 24/12/2019 to return the shoes as they were too big, I arrived at the store at 17:52 and the door was closed, I went inside to request exchange or refund the managers and cashiers were all screaming saying the store is closed due to its Christmas Eve and they refused to assist l, this was the most worst service from Jam
