I used to call different managements many times. Even outside US (Canada, Russia, etc.) Unfortunately, usually it's just a waste of time. First, it's easier for them to mislead your over the phone because the conversation is not documented. Second, as an intelligent and polite person you often fail to ask hard questions which you actually want to ask. Especially when you talk not with obvious scams but with nice people from real companies who try to do their best... Their responses are predictable. Have anybody ever told you: "Sorry, we failed."?
I don't want to turn into board basher (which I am close to based on Meris response). But there are many indirect signs that I don't like here. I may post one more time about the email I received today... and that's it.
