Yep. Don't poke the bear unless you really need the bear to move. The only times I've called back and had original miles credited was when I needed the credit for the original routing, usually in my quest for butt-in-seat (BIS) miles for lifetime status or 1K qualification. Needless to say, it's best to check your account, and see what the actual PQP/RDM credits are, before making a decision.
