It started with escrow and/or weekly payments so it paid for a while then didn't pay? It started May 08, did it pay for the whole first month?
If it did and 2/3 of the posts were made during the first month, the free advertising updown got the second month was not cheap since he overpaid the first month
There was never an escrow for this signature campaign... he paid ontime for the weekly payments, every single time. But there were a couple of unsettled disputes regarding the payment amounts, he apparently missed some member's posts, or missed them entirely.
He didn't miss posts; he paid the wrong prices. If you go through the people he paid and calculate their posts at the time they were to be paid, then divide that into their payment, you'll see that after he raised the prices (and a full week went by) he was still paying based on the old rates.
