Comcast Statement still shows old paid off 4/27/17 amount as Past Due $220.31

Hello,

I really need this cleared off the Comcast Business Statement, it's still showing $220.31 past due. The check was already cashed in by Comcast and payment probably misapplied. Remittance had two clearly indicated specific account numbers and allocated amounts to respective accounts too. Already contacted Enterprise Billing Tech back 8/25/17 but still no response at all.
