If you do not meet the following guidelines you may be charged $75/hour to resolve your issue. Only open a P1 ticket for EMERGENCY Issues with LISTING/ORDERS (NOT ADDING/EDITING) for over 25% of items having a material effect on your business income or if you have received a warning of suspension/have been suspended from channel.
Do you still want to set this as a P1 issue?
