It is our goal to keep customers happy and to resolve any problems ASAP. Therefore, we nearly always respond to e-mails and return calls within 24 hours seven days a week (except holidays). If you do not hear back from us within 24-48 hours, please try again. There is probably a communications problem that kept us from getting back to you. Therefore, it may be best to e-mail us if your first attempt was a phone call or call us if your first attempt was by e-mail.
