Sprint reps: I've found that if you don't like an answer you get from a Sprint rep, just thank them, hang up, and call right back. Recently, I was trying to get a PCS calling plan set up that was $75 for 3000 minutes (1000 peak, 2000 off-peak). The first two Sprint reps I talked to said that what I wanted would cost $109 ($99 + $10 for add'l offpeak minutes) per month. Third time's a charm: the rep found the $75 plan immediately and quickly set switched me to it.

The same goes for rebates, fees associated with equipment upgrades, other promo offers. And presumably with landline FF mileage offers, too. Persistence pays off with these people... Just keep calling and you'll find someone who knows what they are doing (hopefully).
