Do not Order the WP38 - It travelled from CPT to JHB and to CPT again- Issue not resolved

Had an issue with the second phone we ordered. The WP38. Phone kept freezing and camera quality was bad. They collected the phone to run diagnostics. I asked them rather that we please rather upgrade to the WP39 (like mine), we would pay the difference and they can keep the WP38. They said they will first try to fix the phone. Diagnostic report came back that they had reloaded the firmware. We received the phone back yesterday and it is still freezing. This issue has not been resolved. Now the cycle starts all over again... All could have been avoided if they had just collected this phone (in warranty still), credited the difference to the WP39, we would have paid the difference and then they could have sent this new phone. There would be no further issues. Now we sit back where we were right at the start of the whole process. I have sent them a message last night informing them that the phone is still freezing. At the time of writing, no response received
