Samsung J7Pro , MTN Greenstone

So I purshased a J7Pro less than a year ago with MTN and the screen of the phone started filling with ink. I took it to the store where I purshaced it and was directed to the Samsung electionic shop at The Wedge Shopping Centre, Rivonia. Mind you I had a strong phone cover as well as a screen protector and at no point did I drop my phone or handled it roughly, I took good care of it. As far as I know the phone is still under warranty, or so thought. At the end of it all I had to pay about R2 500 for the screen repairs (they said the screen cracked) even though I tried to explain that it’s probably a fault as I’m certain nothing physical happened to it. I’m disappointed in Samsung for making customers pay for their faulty phones, MTN Greenstone for not being of much help and wouldn’t want to do business with them anymore. Save yourself the drama and wasted time.
