We work incredibly hard to respond to all emails within a 12-hour period. Emails are answered in the order they are received during our normal business hours of Monday-Thursday 9am - 7pm and Friday 9am - 1pm EST. Emails sent after business hours and on the weekends will not be replied to until the next business day. After this time it is best to call our toll-free number to speak with a Zone Representative for immediate assistance.
