I had one good experience, and one awful one. I tried to contact Samsung customer service via their so-called 24 chat service. The computer kept routing me in an endless loop, and wouldn't let me chat with a live agent. Eventually, I was given the service number to call - which I did. Once again, on an endless and useless loop. I eventually gave it up. Companies that use these voice recognition computer systems don't seem to realize they have a product that is in its infancy. Maybe in 10 years these systems will actually be able to understand and respond to customer questions and comments. As it now stands, they have the comprehension of a 2 year old.
