I called last week and this week reguarding an RMA for a product I accidentally ordered on a Sunday night. Both times were answered in under 3 minutes.
This being said, we should have the ability to cancel an order online up until it gets processed in the warehouse. I caught the mistake after I hit processor order and it was too late.
