Damaged Samsung S8+ camera

I contacted samsung online as the camera on my 3 month old s8+ stopped working. I was told to go to MM all electronics to get the software updated. This service centre said the camera was faulty and wouldhave a new one by the monday and this was friday. After phoning numerous times I contacted samsung online again to find out my options. I was told by the online agent that according to CPA I am entitled to a new phone as my phone is under 6 months old. I then calledthe call centre a few days later to request a new phone and was toldmy matter would be escalated and someone would contact me. I then phoned again to find out how far the process was and my call was redirected to barbara who was busy, but I was guaranteed she would call me back and I am yet to receive a call. This process is extremely frustrating.
