They did place a charge of $45 on the account but it appears it was credited back later that day after well before it would have appeared on the upcoming bill. It was only listed under Recent Activity since its between billing cycles. Anyway, Charter does indeed place the charge on the account but does credit it back since they determined it was there end, good to know though nonetheless.
Usually the service call is automatically added to your account even before the truck rolls out of the parking lot. However, once the tech completes the work order, it's deducted if the tech reports that it is an outside issue not related to your equipment.
