Terrible service at Totalsports Maponya

My name is Nombuso a Foschini customer. My number is ***.I bought shoes at total sport for my niece as a gift. I bought the wrong size. I stay in Fourways and my niece stays at Soweto. My sister who is my niece mother went to Totalsports-Maponya. The service she received was horrible. She called me and I spoke to Hloni, I explained to him that I am the account holder and I would like my sister to exchange the size of the shoe. He said he won't do it if the account holder is not there. I then went to Fourways and explain my situation to the store manager Zandi. She was so helpful trying to assist. She called Maponya , first of all they didn't answer their phone. Zandi phoned my sister and ask to speak to the manager. They said the manager is not in today. She then requested to speak to the second in charge Kutlwano answered and said she won't be able to to assist her. Bare in mind that my sister had a receipt. Zandi called the area manager the phone was off. She then called the 2nd in charge area manager I think his name is Godfrey. He was off but he tried to call the shop and they didn't answer the phone. I then called my sister to tell them know that the area 2nd in charge is trying to call them. Kutlwano said RUDELY "he won't get through our phone is off " after Zandi finished speaking to Kutlwano my sister told me that Kutlwano through her phone in her face and left her there. I wonder this is the service that we deserve as the Foschini group customers. I am very disappointed and I will never recommend this shop to anyone that I know. I will spread the word that the Foschini group does not give proper training to their stuff. I was also in retail and I have never treated my customers like this. Foschini group should teach their employees what is called treating customer fairly.
