I got linode alerts below:

****************************************
Hello linuxertony! The following activity has recently occurred:

* linode231958 - (13244561) System Shutdown - Completed Sat, 24 Aug 2013 14:08:57 GMT

***************

when I login I found that maybe I forget the password for Linode manager, so I reset it, and
it display — Instructions for completing the password reset may have been emailed to you. —
But actually I didn't get the email. I sought help from support@linode.com and service@linode.com, but no feedback email.

Please tell me what can I do now ?

Try phoning them https://www.linode.com/about/

How to ask for help
1. Give details of your problem
2. Post any errors
3. Post relevant logs.
4. Don't hide details i.e. your domain, it just makes things harder
5. Be polite or you'll be eaten by a grue

I also sent an e-mail to support last night because I lost my 2-factor token, and I have yet to hear back from them about 9 hours later. That is not an acceptable response time.

EDIT: Obs has 1701 posts as of this moment

*whistles star trek theme tune* damn made it 1702

Oddly enough I emailed them the other day and I've not had a response either. Support tickets are working fine though.

Yes, I'll just log into the manager and create a trouble ticket about not being able to log into the manager...

What's going on at Linode? Still no reply to my support e-mail, still locked out of the manager.

We respond to each and every email, usually within minutes. If you haven't received a response from us in this long, then something went wrong. I suggest giving us another shout, or giving us a ring!

I'll send a follow-up mail, but you've got three people in this thread all saying that they never got a response from support via e-mail; you may want to check if you've got some technical problem there.

EDIT: Linode did reply to my second mail to start the account recovery process, and said that they're investigating the reports of e-mail problems.
