Hello Peter, I have been taken from pillar to post by Vodacom and Samsung for faulty phone I bought from them

Hello Peter, I have been taken from pillar to post by Vodacom and Samsung for faulty phone I bought from them. I purchase a new SM-A256EZKDAFA model phone from Vodacom wonderboom. Just few weeks after the purchase the phone was loosing the network. Took it back to them, booked for repairs, came back and was told phone was fixed. Two days down the line same problem reoccurred. took the phone back. It has been months, no one is providing any progress. I had to phone them to find out with no positive feedback. Today after months, I was told sorry we cannot help u, the phone is not faulty. No explanation how they came to the conclusion. What is surprising is that the mother board was changed the first time, which made no difference. Please publish the story, regards
