BAD CUSTOMER SERVICE

So I was called by makro stores about the speaker I brought from them , so today I went and asked for the lady Nthabiseng of which they said she's in a meeting. So I was assisted by a lady with no name tag , I had to ask what her name was she answered and said her name was Siphokazi Khumalo . She took the speaker and after some seconds I got a message from the service company saying I had booked in my speaker . So o asked this lady Siphokazi that I had bought in the speaker for the 3rd time and what if they fix it and after a week it has the same problem ? She than told me that they wont give me a new one , unless that service company says they have me a new one . Not Makro but that service company . So I had told her to bring back the speaker cause clearly after it's faulty again they wont give me a new one , that's when I asked them to bring me back the speaker because clearly after it has the same type of problem after a week . Siphokazi Khiumalo said they wont give me a new one ....The lady by Nthabiseng who is the manager talked to me on the phone and I told her il wait for her to come out of the meeting and she said she was is busy and she wont be able to see me..1st and foremost I'm not getting paid by makro to busy go back and forth wit my speaker,I'm not getting any petrol money to come to them,n surely they not paying for my petrol..if makro wont repay me or give me any other speaker
