Maybe it's an inconvience to support the longtime customers who helped establish the company. But forgetting, or flipping off, those who have been a longtime customer base would not appear to be a prudent way of keeping them.
Just as word of mouth by satisified customers can increase the base, the same word of mouth by long time customers who feel they been told to buzz off may also have the negative effect of eroding that base as well.
Since it appears Acoustica is telling me to leave after being a customer almost from the start, and find a solution elsewehere, then so be it. Don't count on any upgrade revenue here in the future.
