Vodacom is dropping the ball

Hi Peter,im writting on behalf of my pensioner mother,her name is Elizabeth Choeu ,I D ***. My mother is a long standing contract client of Vodacom for as long as i can remember,so in August 2021 she was due for an upgrade and since she resides close to Cleawater mall thats where she goes for any mobile related issues. She was for years using Samsung but in August 2021 as she went in for an upgrade,the assisting agent convinced my mother to go for the Oppo handset and i believe she was adviced that Oppo is exactly Samsung but different name and cheaper. My mother was convinced and she renewed her contract taking the OppoA53s,the technicians helped her migrate her data and that was that. When she got home she attempted making calls and would get succeed in other instances and others not,but she didnt think much of it,it was then later clear that something was off with the mobiles connectivity and she headed back to vodacom 2days after the purchace,she was asked to point out the number she could reach and it would go through when dialed by the agent at Vodacom and she was told it was nothing.The issue progressed and my mother was now a frequent visitor at Vodacom and her frustration was she got the same responce every time and eventually when she was threatening to cancel her contract she was told they will take the handset in but then she must forget about her data or any other settings she currently had,which was enough to discourage her from doing so.I wrote to Vodacoms head office early this year a detailed complained and i only received a ref number for my email and no one has bothered to assist but my mother is paying on time and without fail every month for a handset she has stopped using as its useless,the handset is somewhere in her drawers accumulating dust and she reverted to her old Samsung. I don't understand why they would not furnish her a new handset after complaining countless times and with a track record like hers with Vodacom.
