TErrible service provided because of class

On the 17th of June 2017 my brother Joel Dikotla bought a phone at Pep Polokwane. On the 11th of July it stopped working and was taken back to the shop on the 11th of July 2017. Till date the phoe is still at the shop and no one is willing to refund or give a new phone to my brother. Everytime he goes to the shop he is given a different story and gets sent away. The latest story that was given is that MTN did not give them the phone to give to the client for replacement. It is more than a month now since the phone was taken in. Who on earth stays without a phone for a month??????? Nobody wants to take responsibility, so its either he gets refunded or gets a new phone today or else we will have to take further steps against Pep. We have already started to spread the word on every social media to warn people to stay as far away as possible from Pep if they are not of status because if you are poor you will get poor service at Pep.
