MY WORST PAIN...SAMSUNG GALAXY Z FLIP 3 I bought the phone at Telkom 2021...a week ago my phone went blank it could no longer unlock (when you flip open) calls came through lights of the phone were off the phone has that problem not responding as normal. So I called in Samsung Canal Walk told them what was happening they referred me to 78 Edward street Samsung customer care so that the phone can be assessed.when I got there consultant just looked at the device with her naked eye ...she told me it has a manufacturing fault but the glass of the is cracked so the phone is faulty they won't fix it she asked it she can estimate of how much it can cost for me to pay after fixing R10000 . I took my phone back and I said thank you so much I will never forget the treatment I got from such a big company as Samsung for them not to be interested in over seeing the phone.I will never buy from them again Samsung have very stylish models and is expensive but their products give problems along the run they are not durable at all.
