Hmm that's a super bummer because we want folks to take advantage of our offers without a headache. Did you have existing service with us before you opted for the promo? The credits for the lines on us should appear automatically. For the line that's not getting the adjustment, have you opted for any additional services? The Mobile Internet lines are credited up to $25 so if there's other charges that exceed that, you'd be responsible for the difference. Also, if the plan was changed or lines were canceled, that would also cause the credits to no longer be added. I'm just going over a few common reasons a promo like this might drop off. If none of these are the case, I suggest reaching out to our T-Force team using the social media links in my badge or on our Contact Us page. They are an awesome team that have the resources to look at this further and provide more help.
