I have an odd Starbucks card issue. Mine tops up OK, but one register at my usual *$ shows that the card is "unregistered," and thus I don't earn rewards (it does accept payment from the card), and can't redeem rewards at that register.

The other register works fine... assuming there's a clerk there who is or can sign in to it.

The local store is baffled. The online support is worthless (they just blame the store, saying my card is fine). I've called twice and have gotten nowhere. I'm tempted to report the card lost, have them mail me a new one, and use it instead.
