A NON CARING RETAIL STORE

I bought 2 cellphones at Ackermans Sammy Marks on 20 September 2017 1 of the 2 cellphones was faulty. It never worked I took it Malamulele Ackermans it never got the attention it needed for a month. I then went and took the phone in Malamulele. I called the Sammy Marks store and told them the problem I was advised to bring back the phone as that's where it was purchased. The phone was taken for repairs they took my details and promised to call me. I waited for their call for 11 months. As I wasn't contacted for 11 months I went back to the store on 18 September 2018 I was told Kagiso is the one who works with Cellphones and he is not in. I asked to speak to a manager and a lady was called to attend to me, she promised to call me on the 20th September 2018 when Kagiso is back I gave her my numbers as she requested. She didn't call me the whole day. I then went back to the store, the same lady was shocked to see me. She then said Kagiso is still not back he will be available on Friday. I don't know why I have to always follow up on them as a client. ACKERMANS IS A NON CARING RETAIL STORE. All I want is to get a new cellphone.
