Can take up to 48 hours to hear back from customer service. Most reps seem to have no clue as to what is going on.
From business standpoint, payments are rarely, if ever, on time. It is very difficult, almost impossible to find out if the payments are accurate. If you cancel your deals with them, they will freeze you out of the merchant center, so you can't even verify vouchers that had been sold.
We ended our agreement early December, on vouchers that were to have a 90 day expiration date and somehow are still getting vouchers that are valid. It's odd. But try to speak with someone about it? {sigh}
