Reward Credits expiring soon

My sister's reward's credits (50764) will expire 11/25/12 since she hasn't played in the last almost 6 months.
If she purchases something from TR marketplace will that extend the date by 6 months?
She doesn't have the credit card and won't be able to get to a casino before December.

I know this was previously discussed, but couldn't locate it through search of the forums.

Write to them ASAP, wow she may lose $500.00. Ask them what can u do.

Get the Total Reward VISA card and charge something on it...
that's as good as playing and you'll never loose your points.
I have my monthly AT&T phone bill set for for automatic VISA
payment on the card...No worries/points always stay good.

Can she overnight her card to someone and have that person put a couple points on her card before Nov. 25?
