Is the invoice the paper that says something like "this is not a bill, your insurance has been billed? Seems today eveything ends up costing more and I cringe when I get that bill in the mail.I understand the difference between a statement (EOB) and an invoice. I'm not that dense. If deb received an invoice, then she should pay it and not wait another 3 weeks. Very irresponsible of her. I'm glad I don't do business with her.
