CARFAX.com Paused Unlimited account for EXCESSIVE USE? Internet

I am signed up with Carmax.com for an unlimited account, this lasts 30 days so you have to look up all potential cars within that time to get your money;y worth. I live in Chicago so thier iss a larger selecytiom of used cars when you add the suburban dealers to the mix. Right now my account is "PAUSED due to EXCESSIVE USE." And the only way to contact these idiots is bt email. Here is their response during prper business hours:
