I got my Samsung A8 last December and subsequently was in and out of the Samsung repair shop about 10 times in the 7 months that followed.
Endless replacements of parts, motherboard and the glass, which was scratched by them during one of the repair jobs.
In the end, the phone had become a Frankenstein, a mix of patches, repaired original parts and spare parts. It was a mess and still didn't work properly. One day, the entire frame popped out of place and I was left looking into the phone's innards...
At pretty much every turn, they were late with the repair and I'd showed up for nothing.
Once - get this - the repair shop had closed, as in closed
permanently and moved elsewhere. But they hadn't bothered to let me know. So when I showed up to collect my repaired cell, the shop was boarded up! When I called Samsung Support, they had no idea where my phone was. But the lady promised she'd try and find out what had happened to it.
It was an utter nightmare.
One of the times I went up there to collect my phone, I'd first swung by the mall's security staff and asked them to join me, as I knew Samsung would give me the run-around again and I needed impartial witnesses to see it all go down. Well, right before leaving the Samsung repair shop - empty-handed once again - the two stunned security guards told the Samsung people to have their shit in order next time or they'd be reported.
When I'd had enough, I let them have it bigtime right there in the shop. They threatened to call the police, which I asked them to please do over and over during my rant, but, alas, they never did.
After this ugly episode, they told me I'd get a new phone in two weeks. About a month later, they called to let me know I could pick up the new phone, an A7, which actually is an upgrade.
I still feel obliged to inform Samsung HQ, however. It was my worst ever experience as a consumer anywhere, by far.
