Unacceptable, childish behavior from Samsung

I booked my Note 4 in for poor battery life on Wed (23/03) to be diagnosed and repaired under warranty. Today (29/03) I called in to check if the phone was done and ready for collection. They told me that it was and so I went to collect it. <br> The queue for collection was very short and I was almost immediately assigned to a consultant who told me that he would go and bring me my phone and that I should just wait 5 minutes. Thereafter he returned and said that they were still busy with QC and that it shouldn't take long. <br> After 15 minutes, they realised that they were busy testing the wrong phone. So they 'found' my phone and started on it.<br> Half an hour later, they told me that my phone will in fact not be ready today and that I should come back tomorrow. Also, they can't tell me why its not ready, only that I need to home and call the technician who will explain the situation to me. When I asked to speak to the technician in the store instead of going home and calling him, they said that he has gone on break .<br> I went home and called the technician who told me that the front camera was faulty after they completed the repair and they need to replace that.<br> I think that this is pathetic
