I said my service experience with Apple was bad, not the whole planet. See the difference?
The point I was making was that my personal experience with Apple customer care has been bad, but I'm not assuming their organization suffers from shoddy customer care; I'm giving them the benefit of the doubt.
I don't know if there is a problem with Zeiss customer care based on what we've heard here. As I said before, perhaps the OP caught an employee on a bad day. Perhaps I caught some Apple people on a bad day too. No reason to tar and feather Apple (or Zeiss) based on a sample of one.
