On the balance 4200 points is roughly a few magazine subscriptions so you're not really 'losing' much anyway if you can't find a means to redeem them for travel.
OP isn't trying to save 4240 points but wants to know how to get 4240 points into account (presumably to redeem an award).
Easiest and fastest way is to buy them ~$150
Look at these to see if they help.
