Did you ask the ADA rep about the compensation for the people already signed up?
It's interesting you bring this up coz I have issues with this in just about every area: I can't get the introductory price for digital cable because I'm already a cable customer even though I'm not a digital cable customer, I can't get the special price for the cable modem coz I'm already a customer, I can't get the free checks for life at my bank coz that's only for new customer, and so on and so forth. I appreciate they want the new business - but why not take the steps to keep the business - or reward the people - you've already got.
Ask him - the worse that happens is he/she says "it only applys to the new people"!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
