We have staff on phones and emails all day but only during business hours. Some customers have complained that we don't pick up the phone and when I personally check the phone records I discovery that they call on weekends and in the middle of the night!!
As posted in our contact page we are open 9am to 5pm Eastern Standard Time Monday through Friday excluding Holidays.

Also sometimes we have company-wide meetings or lunches and phones may not be attended. And if you call between 4pm-5pm you'll likely not get through for some strange reason everyone calls just before 5pm and all our guys working the phone.
And if all our staff are on the phone you'll be redirected to voice mail.
Emails are typically replied to 24-48 hours but during peak season it may take longer. But do know that if you email us every few hours (yes this does happen) our system puts you in the back of the queue because the most recent email may be an update to the previous email so yes you get put in the back of the line if you email us once every hour.
Lastly, if you fill out the contact page instead of emailing us please please put your CORRECT email and phone number. So many times we reach out only to find out your contact info is missing or incorrect. We've had some people complain that we weren't getting back to people and I personally investigate this and it turns out contact info was wrong or missing.
One more thing, we also had lots of people repeatedly say we aren't replying to emails but we discover that our replies (all very prompt) have gone to your spam/junk filter. I know earthlink automatically does this as does other ISP's.
Hope this helps clarify.
