Vodacom is a ****

My dad took a contract for my younger sister, six month down the line her phone stopped working and we took the phone back to Pep store in sannieshof. The phone was booked in and a week later ,we have to pay R1500.like what the hell why pay R1500 for a phone that costs R1800 cash price? Samsung A05. While we were there the consulted was very rude.and only to find out it wasn't us only that has an issue with their phone. Are they selling rejects to the community? Or is it a scheme to make money out of people 🤔 . They us this number to call ***. They want their R1500 nothing more or less just money. Why the hell do we have insurance and warranties? Vodacom is a **** 😒
