Billing reminders: how much is too much?

I have a server with a well known company here (no names), and it renews early each month. I pay on time, without fail, but chose not to have a CC on file with them. On the 8th day after paying (on the due date), it generates the next month's invoice, sending me a notice email that it couldn't apply payment because there's no card on file.
8 days after paying (~22 days before due).
6 days later, another notice (~16 days before due).
Then one per day, every day (10 so far this month), until it's finally the next month again and I pay it, starting the cycle again. Frankly, it's getting so annoying I'm considering moving providers. Told them, they whined about how they have to pay their providers (but obviously not for this box they sold me) far in advance so I should basically buck up and take it.

I create invoices 14 days in advance and send a notice, then 7 days out, 3, then 1. 4 times, more closely together as the due date draws near seems proper, but I'm not selling dedicateds as they are.

I wanted to get people's take on it. Would you consider this constant badgering excessive, or par for the course when dealing with dedicated server sales? I have boxen with several other companies, and this is the only one that feels they need to browbeat the customer in this manner to ensure payment.
Thoughts?
