Hey @waqarabbasi01,
Welcome to the Community!
Our promos and prices can change at any time and without notice, therefore it's possible that the previous offer is no longer available. Your online account will always have the most up-to-date promotions available for your own account. We suggest taking advantage of an offer as fast as possible as they're always subject to change.
If you have questions regarding the available upgrade options for your line, please don't hesitate to reach out to us through these channels
