Reportedly today per multiple reports on reddit
It did indeed expire yesterday.
I spoke to a rep, apparently the offer was a surprise for them as well, they got over 2000 backlogged calls. In a meeting this morning they decided to implement a tracker for anyone who tried to get the line, a rep can add your line to the tracker and then they will add the free line. I got it added to a new business line today. (usually they don't have a wait time yesterday, it was 45 minutes)
Confirmed that
all the lines need to be kept for 12 months.
As for the 2022 Switch P9 it isn't eligible on this line, but got it for 3 of my other lines. Thank you
