Here's what I calculated for a pair of 100 level seats:
The cost for a pair for 3 ALDS ($250x3) and 3 ALCS games ($450x3) would be around $2100. The installment structure had us pay around $3998 (3 payments including the initial $500 deposit), which would include a portion of the World Series. Therefore, we should be owed back roughly $1900. I'm not sure how the Wild Card factors into this, since it didn't seem to add up. I believe we paid for 11 potential home games, but it should be 12 if you include the Wild Card.
For the individual series purchases, we should be refunded Game 4 of the ALCS and the entire World Series. I bought a pair in the 500's, so that would mean an additional $1540 refund.
