Poor Service at Cell C

I bought a cable charger at Cell C in Pinetown Pine Crest mall on 26/10/2020 helped by a consultant called Moses Mthembu and 4 days later the charger stopped working and by that time I was already in Richards bay so I went to Cell C in boardwalk mall to return a charger and they told me that they did not have stock but as soon as they get it they will courier the cable to me. They took down my details and promised courier my cable. I waited for about a week and no one contacted me regarding my courier and I decided that I call them instead. When I called they told me that they have handed the matter to the branch where I bought my charger which is Pinetown so I must be in contact with them because they are the one who are handling everything. Today (29/12/20) I decided that I go to Pinetown and when I got there I experienced a very bad service from the workers of that branch. I explained everything to them and they just responded by telling me that their branch manager is on leave and they know nothing about the matter so I must come back when she is back from leave. No one was willing to help, they just watched me standing there as if I was some sort of *******. I even called the Richards bay branch my self because I left the cable with them on 01/11/2020 because the employees in Pinetown just told me that they know nothing about the matter and they are not able to help me. I left there without my cable charger, nothing what so ever.
