disgusting attitude

We bought a phone from pep cell northgate and the phone was faulty and we returned it. For some reasons we were told to buy airtime so that they can check what is the problem. Then we couldn't be assisted as the manager was unavailable. We went back after 4 days and the same thing happened we were taken from one corner to the other. We had to use our own airtime to get hold of managers as the store consultants could not. I'm really disappointed by the way the manager handled the situation. And we done to Catherine Mataboge who kept us calm and did her out most best to assist.
