AOL has a bad reputation for not delivering emails. As, initially, you didn't tell us that you had received an automated response people would assume that the problem was at your end.
Tickets don't normally get forgotten but if you keep posting additions to the ticket to chase it up that will actually keep putting it to the back of the queue.
(The software will sort tickets by date)
Two possibilities:
1. It is a complex problem which is taking time to resolve
2. AOL failed to deliver the response.
To eliminate (2) check the ticket on line. As you have had the initial response you have got the ticket number.
There have been replies to your ticket. Also, your name servers are now working. Once a domain name has expired it can take up to 72 hours for changes to take effect after being renewed.
Please also note, that we deal with tickets from oldest to newest, every time you reply to a ticket it gets moved in our ticket que. You also only need to open one ticket. Please wait for our support team to answer your tickets before adding anything else.
You can also manger your own name servers by clicking on the domains tab. Click your domain name and than select "Manage nameservers."
