Neve ever Buy Cell phones at Truworths especially CTruworths Carnival Mall

On Monday 25 May 2020 O went to Carnival Mall Truworths to buy a cell phone. Gentlemen on duty assisted me and he was very professional, he assisted me very well. I bought Nokia 3.2 and I was very Happy since I was struggling with my current phone. The gentlemen's explain the terms and conditions and the guarantee of the phone, and I accepted them and sign and everything was fine I left a very happy customer. problem started when I reached home and then my phone started loosing network then. I thought maybe it's the settings so I bought data and stated updating everything the problem kept on persisting, it will loose network for about two hours even if I restart it it doest want to work I have to take out the Sim card and insert it again then restart it again in order for it to work. On Thursday I decide to take the phone back to Truworths and explain to them that this phone gives me problems and I have tried everything I know but the problem Keeks on coming bak. The Lady. Who assisted first ask what have I done to phone of which I didn't take it kind of her accusing me that I have done something to the phone, they kept on calling one another as I was waiting until another guy came and took the phone to the back after some time he came back and said they won't change the phone they will take it to repair I asked what about the 7days exchange because clearly the phone had a broblem then I asked for a Manager, then the Ladyanager who was on duty came and she was worse that her staff members she said to me they won't change the phone because there are scratches at the back of which I didn't see. She said they will take the phone to repairs because I have damaged the phone and now I expect a new phone they won't give me because the phone is damaged as we were busy arguing she took the charger and put it on the box and left. It was the worse customer service ever ,now I have to use a phone that just loose network anytime without me realising and I will loose important calls. I tried calling Truworths customer care line no one is picking up and I am still with that phone I will never buy at Truworths because they their Manager don't know customer service.
