Bad service @CNA Maponya mall

I have never been treated with such disrespect I bought a phone at CNA on the 07/12/2018 hurricane edge the phone started giving me problems and I had to take it back.but because it was after 7 days they said they will book it in for repairs that was on the 19 /12/2018 my fone was booked for repairs .I went back on the 07/01/2019 I was told that the fone was taken inn for repairs and they had no ideas when the fone will be fixed .I've been communicating with Anna at maponya she also tried to assist me but she couldn't because she tells me that where they sent the fone the people are not sure when my fone will be fixed I've since proceeded to asking for the manager to see of he could assist me but even now I still don't have a fone and no one seems to know when the fone will be fixed my frustration is that I brought the fone new it did not break there was a techinal issue where it switches on and off. I would like someone to assist me and advise which steps I could follow its been more than a month now.and the way things stand I can still wait some more days since no one is able to tell me exactly when my fone will be sorted .I'm so frustrated and feel disrespected because no one is assisting me
