Stinky attitude from the manager

Hi my name is s bongiwe I bought STK phone at Ackerman's store on January then on august I had a network failure n the battery didn't last I took it back to the store they took it to the repair centre.........I went to fetch it only to found that out t was not fixed because it had the same problem I then went back again I met with the manager #Chantel she said maybe its the battery she then gave me a new one bt still it didn't work I then went to Chantel again she said she wil take it back to the repair centre I asked her how wil the repair centre fix it when they failed first I thn told her that I wil report the matter to hello Peter she thn asked if do I have the contact details so she could give me.......what kind manager does that to the customer
