$20 off Unlimited Plans promo not working on multi-line group?
I have a Multi-Line account set up currently with 3 members. 2 are on a $50 prepaid plan and the 3rd is on the $65 unlimited prepaid plan.
Currently, there's a "$20 off Unlimited Plans with AutoPay" promo (ending Jan 9, 2020). Based on the multi-line tool (https://www.att.com/att/prepaid-multiline-discount/), the total monthly rate I should be paying is $105/month. However, my account is not reflecting the additional promo and my total monthly rate is $115/month.
