No help from infusionsoft support desk since October.

@Chantelle_Fraser, I’ve contacted Support leadership to look into the issue.

Hi Chantelle,

My name is Blake, from Advanced Support. I just emailed you about this from case 1012601. Take a look at the information I sent over and let me know if that helps resolve it for you.
