I'm willing to see it as a typo Chad Brodgesell. They are in agreement that the matter regarding the customer is complete.
I posted this for 2 reasons: 1. To determine if they have deliberately misinterpreted the invoice & explanatory letter I sent and to show how they try & confuse the situation &/or imply there is only a customer relationship. 2. To see what else I need to do to get my point across to them, or if there are any obvious errors and or confusion in my reply.
