Going back on promises

I recently upgraded & got a LG G4 handset.<br> <br> Within the 2nd week after getting it I noticed that some of my photos were *******ing. I hoped that this would be fixed with the next software upgrade & didn't complain.<br> <br> Around 10 days ago my phone got very hot. It restarted every 2 minutes & I couldn't use it at all. I took out the battery & went back to using my old phone. I charged the old phone with my new charger and it completely destroyed the battery and the camera.<br> <br> Vodacom store said that the phone would be fixed, but I complained that I didn't want a fixed phone as this issue is bound to happen again. I don't even want to stay with LG as I'm not happy with the product at all.<br> <br> The manager, Shanaaz, told me that it was okay, she would log an escalation when sending the LG in for repair & I could get a new Samsung handset as it was within 6 months of the upgrade.<br> <br> Today I phone the branch to ask when I can get my new handset. Shanaaz wasn't there & the manager on duty told me that I couldn't get a new handset and had to take the fixed one.<br> <br> This is UNACCEPTABLE. I was told that I could get a new handset. Why are you not delivering on your promise???? Very unhappy
