For many transactions, the only customer support I need is an automated shipping confirmation, automated tracking, and maybe (or maybe not) a way to return/refund.
I buy a fair number of items on AliExpress and banggood. I don’t want “good customer service” bloating the costs. (Ironically, I still get good service on the 1% of transactions that go wrong, even when I can’t really prove anything. I bought two nice lipo chargers and got sent one. One email and remedied in a couple of weeks.)
I've never had a good customer support experience on AliExpress. Mostly because the only times I've needed "customer support" was when I've been sent fake items (specs grossly and explicitly misstated, usually, often with clear intent to deceive), and that is something AliExpress sellers will absolutely never admit to doing in my experience. Best case they politely say there's no problem, worst case they throw racial slurs based on your presumed nationality based on the destination country (which isn't even correct for me, ha).
In those cases, AliExpress will seemingly randomly decide for or against you randomly, even when you file a dispute with clear photographic and video evidence. I've had it go both ways.
90% of the time it's fine, though, and the cost savings outweigh the loss from fake goods. But I'd certainly not call the AliExpress CS experience "good".
