E-mail deactivated due to DSL services suspended
NOTE: Please read the entire thing. And I beg of any of you to post only constructive and meaningful answers/solutions.
Backstory: My grandfather used his old e-mail to buy me a video game from an online retailer. The mail itself had a key I had to use to activate the game. A few years later, my grandfather passed away. Because of that, we canceled his AT&T DSL services. Unfortunately, I was unaware that his SBC Global e-mail tied to the DSL service would be terminated as well. Some time between then and now, I had lost the key to the video game, and the only way to get it back is to have it resent to the e-mail address you bought it with. This leads to my main problem.
My problem as of right now: The key for the video game I detailed earlier can only be recovered by being resent to the e-mail the video game was purchased with. Considering the e-mail is suspended, it is impossible to access the key, along with anything else on the e-mail. Before we cut straight to the solutions, I have already tried the following: call AT&T Tech Support's Call Center, have back-and-forth e-mails with AT&T Tech Support employees, as well as Yahoo! Tech Support employees, and I have also tried doing that option where it gives you a choice to sign up for another e-mail. All of those solutions did not work.
My solution: I think that a possible way to fix this problem is to completely delete the old account, and then allow me to sign up again with the same exact e-mail adress name.
Another possible way to fix this problem is to forward e-mails from CERTAIN senders to another e-mail address.
I will provide information on the old e-mail account, but because this a public forum, I will only reveal information to actual AT&T employees or other trusted community members who Private Message me due to privacy reasons and personal information.
