That's probably the reason I still prefer Anker to others offering similar technology, because when there is an issue it is resolved satisfactorily quickly.
Well I doubt it is a pan-UPS issue, personally I have only good experience with UPS. I had worse experience with USPS which I traced to an individual who was just sloppy, reported that individual and they vanished to be replaced with a flawless post person. I don't think you should make blanket decisions but focus on individuals. If this is an individual fault then everyone, such as you, complaining, will triangulate within UPS to the bad individual. That individual could have been made to fail via too high expectations (too many parcels, too big an area, etc) so let UPS fix itself by giving them knowledge of failure. It would be bad to hurt other good UPS individuals.
Two other off-topic points:
- I seek to really avoid in-a-hurry purchases if at all possible, in the case of typical Anker products I'm either mildly curious or have been thinking for some time, I assume a couple of weeks usually to get (and for it to break and warranty replacement).
- I buy with very good credit card protection and I'm allowed, without any reasonable evidence, claim on the CC insurance upto an annual limit so my worst case is never out of pocket.
