Seattlehifi,
thank you for your offer of assistance. i am almost certain that an old number is not the problem. while i have generally gotten an automated general annoucement when i called the number listed on the wadia website, there have been a few occasions (i have called numerous times) when a human operator answered the call. one of those occasions was on friday. the automated general announcement gives a list of departments and extension numbers to dial to reach the respective departments. when i entered the extension for the service department, i invariably got another message stating that the person in the service department was unavailable and to leave a message. the problem is that when i left a message i received no return call. on a previous occasion when i got the human operator (who announced that the company was wadia) and asked to be connected to the service department i got to the same announcement (the one about the guy not being available...).
on friday, when i again got the human operator, i specifically told the operator that i was having difficulty getting a person to pick up the call when i contacted the service department and did not getting a return call to the message that i did leave. in response, the operator told me that she would try someone else. but what i got was the voice mail announcement of another person who was apparently not available.
what made this all the more bizarre was that i hung up when i got yet another voice mail announcement and called the main wadia number (at least the one listed on the website). this call was maybe 1 minute after i spoke to the human operator, but this time the call range to the automated general announcement. i made several repeat calls within a period of 20 minutes or so and got the automated general announcement every time (on some occasions the announcement stated the name wadia and on other occasions it stated the name audio research).
this is the kind of stuff that makes me really wonder about exactly what is going on at wadia. based on what you are stating (and i checked and wadia was bought by fine sounds about 1-1/2 years ago and bought sumiko about 1 year ago; they apparently also own audio research), my suspicion is that the human operator (when i actually get her) is not actually located in michigan (or wherever wadia is operating these days). what is even more worrying is that when i got the automated general annoucement, i tried different departments to see whether i could get anyone to answer at any of them, and i did not. one of the departments that i called was the sales department. i would suspect that one department that you would always want to have pick up the phone is the sales department, so when you can't get the sales department to pick up the phone, then something very odd must be going on at wadia. when i first bought my unit 2 years ago, i never had a problem getting someone to answer the phone at wadia. now, i apparently can't get an answer from any department at wadia.
