Hi there! @Donald55 thanks for posting your concerns. I’m sorry to hear your phone went missing.
I’m afraid that because of the nature of GoPhone services we are unable to extend any plans that expire as they are non-refundable. Please keep in mind, if you’ve opted for the 60.00 monthly plan you will get carry over data for one 30-day renewal period.
For more information, please visit us at http://www.att.com/shop/wireless/plans/prepaidplans.html
We apologize for any inconvenience this has caused.
