If you are using Hotmail/Yahoo email then you will not get a reply from us as those services treat our email as SPAM. If you manage to get something from us, it will be in your SPAM folder. It can take up to a week to get an email at those services due to how their SPAM policies. We cannot alter their policies, nor can we make them deliver email if they chose not to.
Could also be your email was filtered out by our server. Many things can trigger that. Most of the time it is due to some attachment that should not be there (i.e. spyware, malware, XML scripts...). Usually happens when people try embedding an animated GIF in their signature. I can find out more details tomorrow.
We answer our email within 24 hours of receiving it, Monday through Friday. If you send an email after 5:00pm CST on Friday, or Saturday, or Sunday, it will be answered first thing on the following Monday morning. We answer our phones Monday through Friday between the hours of 8:30am and 5:30pm CST (GMT -6).
You certainly can delete your account through the game. If the hours of our phone service is not within the hours you can call us, then you may also PM us on the bulletin board. Do not post your account login ID on the bulletin board as them anyone could access the account information.
If you are unhappy because you think you are not getting any help, we have numerous ways to help. The bulletin board, the WEB site, the trainers and associated sites are all available to everyone. The in-game "Help" channel depends on someone being on that channel at the time you are on. It can be hit or miss.
