Those figures don't add up.... You have 4 paid lines, 5 free lines and you're getting $40 autopay discount which only applies to paid lines -- would need to be 8 paid lines. The $54 Insider Discount also doesn't add up since you're only paying for 4 lines.

I do have kickback on the 5 paid lines, they wouldn't budge on adding them to the free lines.
